Abstract
The present invention relates to hevy diamond, which is one of synthetic diamonds and features that C13 isotope is used as its main component. Its advantage is that its performance such as high-temp and abrasion resistance is superior to natural diamond, so it is more rare and noble.
Description
The present invention relates to heavy diamond, which is a synthetic diamond.
Existing synthetic diamonds, like natural diamonds, are generally composed of the natural carbon element, carbon-12 (C: (C-12))12C or C-12) is an isotope of its main constituent element.
Thus, synthetic diamonds do not surpass the characteristics of natural diamonds.
The purpose of the invention is: a synthetic diamond is invented which has a superior characteristic to natural diamond.
In order to achieve the purpose, the invention adopts the following technical scheme: the heavy diamond is one kind of synthetic diamond, and is characterized in that: it uses carbon-13 isotope as its main constituent element.
Compared with the prior art, the diamond has the advantages of better composition than natural diamond, higher rareness, higher value, higher temperature resistance, higher wear resistance and the like.
The implementation method of the invention comprises the following steps: the diamond can be synthesized by using carbon-13 graphite or other raw materials, or using gasifiable carbon-13 raw materialThe feed (carbon-13 methanol described below) was produced directly by the gas phase process. Carbon-13 graphite is a synthetic graphite named because it employs a carbon-13 isotope as its main constituent element. It can be prepared by the following method: firstly, compounds containing only one carbon atom are used as raw materials to enrich carbon-13 isotopes by means of isotope separation means such as rectification and diffusion, and methanol (CH) is usually used3OH) is realized by rectification (including vacuum rectification) and the like, which mainly results from that methanol is a raw material produced in large quantity in industry, has rich sources, and can be produced by rectification process. Then, the methanol rich in carbon-13 is fully combusted and oxidized into carbon dioxide, and then the carbon dioxide is reduced into carbon powder by magnesium, and the carbon powder is obtained by adding additives into the carbon powder according to the proportion of the graphite raw material for synthesizing diamond, compacting and roasting. This process comprises the following two equations:
the heavy diamond mainly has a so-called heavy isotope effect (also called the mass effect of the isotope) because the isotope of carbon-13 which is the main component element of the heavy diamond is the heavy isotope of carbon, and is a slow phenomenon which is correspondingly presented by the property of a substance along with the increase of the mass number of the isotope of the component element, such as melting and boiling point rising, chemical reaction speed slowing, and for a superconducting substance, the critical temperature can also be improved, and the like), and the heavy diamond displays the characteristics of temperature resistance and wear resistance; and because of the composition and the property which are beyond natural, the (synthetic diamond) can be more rare and valuable.
