Description
[technical field]
The present invention relates to the electronic glass technical field, specifically, is red solder glass of a kind of doped with nanometer oxide and preparation method thereof.
[background technology]
Nanometer is a yardstick notion, be one meter part per billion, physical connotation not.When material after nanoscale, the performance of material will be undergone mutation, and property occurs.Since the nineties, nanotechnology is with its novelty, uniqueness, demonstrate out fine application prospect, and obtaining a series of key breakthroughs because there are the factors such as possible range of greatly imagining space, developing prospect and hiding dramatic change in this field, its research has received the concern extensively and highly of various countries, the whole world with application.
Before the sealing property of setting forth relevant interpolation nano material change glass, be necessary at first to introduce the feature structure of nanocrystal, because these special constructions are bases that it produces unique chemical character and has the particular chemical performance.Nanocrystalline structure is different from conventional substances, mainly contains two class views at present about the nanocrystalline structure feature: the first kind thinks that the nanocrystal interface has " class gas " structure.It both had been different from the crystalline state of long-range order, also was different from the non-crystalline state of short range order, but was in the higher state of a kind of degree of disorder.Second class is thought and is had shot-range ordered structure in the nanocrystalline structure.Because the factor of decision nanocrystal interface structure is a lot, as relevant, also relevant with factors such as nanometer particle process method, pressing processes with the distributional pattern of the kind of material, size of particles, nanocrystal.Therefore, relevant nanocrystalline structure is determined by quite complicated inside and outside multiple factor.
At present nano material is had two kinds of sorting techniques, the first is divided into two classes with all nano materials from structure, and first kind nanometer material structure is all formed by crystal grain and two kinds of structures of crystal boundary, and all structural motif sizes all are nanometer scale.The concentration of material median surface is very big, can reach the over half of whole volumes, this high density interface structure makes material have structure closely, thereby changes in material properties is huge, the X-ray diffraction of this class material shows the diffraction peak broadening that causes because of grain-size is little, and the broadening degree is observed Scherrer formula I
Hkl=k λ/β cos θ, second class is the random network structure that low density has a large amount of nano-scales cavity, this type of material entire infrastructure also has nanometer skeleton structure and the littler metastable atom cluster of ratio nano crystal grain to form by nanocrystal and nanometer space sometimes, its density is low, this class material characteristics is to have huge random network structure, and complicated passage and pore space structure are wherein distributing.Surface tissue concentration is very big in the material, can reach (20～50) %, also has a large amount of interface structures simultaneously.The surface tissue atom of high density has greatly changed the performance of material.Second kind of classification is to be divided into four classes (1) zero-dimension nano crystal by the nanocrystalline structure form, it is nano-scale ultramicron (2) 1-dimention nano crystal, promptly grain-size is a nanometer scale on the one dimension direction, film or synusia structure as nano thickness, or unidimensional fiber (3) two-dimensional nano crystal, promptly grain-size is nanometer scale (a 4) three-dimensional manometer crystal on two-dimensional directional, refers to that crystal grain is nanoscale (nano crystal material of indication usually) at three-dimensional.The interface structure of nano material and surface tissue can influence the character of material, simultaneously, the interface structure and the surface tissue of material are carried out suitable modification, also can change the chemical property and the performance of material effectively.
More about the exploration of nano material's structure characteristic research, as free volume type defective and nanometer space, structural rearrangement, dot matrix contraction and the red shift of atomic vibration frequency of nanocrystal, in addition, ultramicron has the multiple twin structure of symmetry five times.Free volume type defective is a kind of shallow gesture of catching, but can account for more than 90%, and along with grain coarsening, the significant variation will be taken place for the size in nanometer cavity and concentration, and such defective will produce influence greatly to the interface structure and the performance of nano crystal material.The STM sweep current makes the super cluster that exists in nanocrystalline present that trend is arranged and structurally ordered, but structural rearrangement does not then appear in atomic force microscope research.This shows, can make anisotropic motion under the situation far below melting temperature at the crystal boundary of nano-solid under the tunnel current effect, and HREM and STM is very effective to the Study on Microstructure of nano material.The interface structure of nano material determines and affects the character of material, the factor that influences the nano-solid structure simultaneously is a lot, nano amorphous silicon nitride at high proportion in the interface formation of the outstanding key of silicon be subjected to principal mode and donor-type local attitude energy level relevant, conduction band electron is same to be subjected to the compound of principal mode defective local attitude hole-recombination and donor-type defective local attitude electronics and attitude hole and the Ultraluminescence emission peak that produces corresponds respectively to.
When the size of particle is reduced to nanometer scale, will cause sound, light, electricity, magnetic, thermal characteristics to present new characteristic.For example: the II-VI family semi-conductor sulfuration cadmium that is widely studied, the position at the peak of its absorption band border and luminescent spectrum can reduce and remarkable blue shift along with grain-size.According to this principle, can obtain the Cadmium Sulfide of different energy gaps by the control grain-size, this will greatly enrich the research contents of material and be expected to obtain new purposes.We know that the kind of material is limited, and the Cadmium Sulfide of micron and nanometer all is made up of sulphur and cadmium element, but by the control preparation condition, can obtain the band gap material different with luminosity.That is to say, obtained brand-new material by nanotechnology.Nano particle often has very big specific surface area; this solid specific surface area of every gram can reach hundreds of even thousands of square metres; this makes them can be used as highly active sorbent material and catalyzer, in fields such as hydrogen storage, organic synthesis and environment protection important application prospects is arranged.To nanometer body material, we can summarize with " lighter, higher, stronger " these six words." lighter " is meant by means of nano material and technology, and we can prepare the constant even better device of the littler performance of volume, reduces the volume of device, makes it slimmer and more graceful.First computer needs three rooms to deposit, just by with micron-sized semiconductor fabrication, just realized its miniaturization, and popularized computer.No matter from the energy and the utilization of resources, the benefit of this " miniaturization " all is very surprising." higher " is meant that nano material is expected higher light, electricity, magnetic, thermal characteristics." stronger " is meant that nano material has stronger mechanical property (as intensity and toughness etc.), and concerning nano ceramics, nanometer is expected to solve the fragility problem of pottery, and may show the plasticity with materials similar such as metal.
The lead-free low-melting sealing glass product form is a powder, and it forms sinter through high temperature sintering in the fabricate devices process.Thereby the powder preparing technology can be used for the sintering of lead-free low-melting sealing glass.Simultaneously, can adopt methods such as chemical vapour deposition to prepare seal glass.In this external compound lead-free low-melting sealing glass, filler can be added with nano-scale powder crystallisate,, and play beyond thought effect with consumption seldom.Can also utilize the amorphous coating technology, the powder surface that has characteristics such as negative expansion at some coats lead-free low-melting sealing glass, thereby on performances such as chemical stability, thermal expansivity lead-free low-melting sealing glass is carried out modification.
The present invention utilizes the unusual character that surface and aspects such as interfacial effect, small-size effect, quantum size effect and macro quanta tunnel effect presented of nano material and shows some excellent performance, improve the sealing property of seal glass, its excellent performance is embodied.Science and technology and social progress require the composition of low-melting sealing glass to develop to pollution-free and low fusing directions such as lead-free and cadmium-frees.China studies less aspect nuisanceless seal glasses such as lead-free and cadmium-free, along with China joined WTO, also should actively develop the research of nuisanceless seal glasses such as lead-free and cadmium-free.Seek new glass-former system in addition, set up new glass and form theoretical and structure theory, adopt new technology of preparing will become the direction of lead-free low-melting sealing glass research and development from now on.
