Abstract
A preparation technology for life diamond is prepared according to the following steps: in vacuum, a reducing atmosphere or inert atmosphere, performing high-temperature processing on human body or animal wool, so as to extract solid carbon from human body or animal wool; immersing into a strong acid or a strong base to remove impurities, so as to perform purification processing; then under a metal catalyst, nonmetal catalyst or catalyst-free condition, generating a diamond fine powder or particle at a high temperature under a high pressure; taking the generated diamond fine powder or particle as a raw material, and generating a jewel-grade large-particle diamond monocrystalline at a high temperature under a high pressure by utilizing a crystal seed process; and performing cutting processing on the jewel-grade diamond monocrystalline to form life diamond. The diamond monocrystalline is grown by utilizing extracted solid carbon for directly generating the diamond powder and then taking the diamond powder as the carbon source. The method saves a graphitization process, and is beneficial for reducing cost in the production cost.
Description
Technical field
The present invention relates to diamond preparation field, specifically, relate to a kind of with the carbon extracted in human body/animal hair or other animals and plants organism for the method for diamond prepared by raw material.
Background technology
Diamond is made up of carbon, has the crystalline solid of cubic structure.Diamond has the highest hardness and pyroconductivity in known all material, is widely used in various industrial processes and semiconductor heat-dissipating industry.Gem Grade bulky diamond is generally referred to as diamond after cutting processing.
Rough diamond is formed under the high temperature and high pressure environment of inner about less than 150 kilometers of earth mantle, and the motion with volcano eruption and the earth's crust is brought to earth's surface.
Because of the visual effect that it is hard, rare and dazzling, be described as " king of jewel ".
Carbonado is in nineteen fifty-five General Electric (U.S.A.) (GE) company, and by graphite and iron, cobalt, the metal solvent of the periodic table of elements such as nickel the 8th race, at HTHP, (pressure is greater than 5GPa, and temperature is greater than 1200 DEG C first.) successfully synthesize under environment.The seventies in last century, GE company temperature differential method (crystal seed method) successful growth goes out carat level bulky diamond monocrystalline.The nineties in last century, Japanese inorganic material research institute has delivered carbonate, sulfate, salt, sulphur, the nonmetallic materials such as phosphorus change adamantine method as catalyst from graphite, but the method needs higher pressure (being greater than 7GPa) and temperature (being greater than 1700 DEG C).
China Patent No. CN101124158A discloses and extract carbon from human body or animal ceratin (comprising hair), and then a kind of method of diamond growth at high temperature under high pressure.China Patent No. CN101171987A discloses and extracts carbon from human body or animal hair, and then diamond growth at high temperature under high pressure.But this patent does not announce concrete implementation method.China Patent No. CN104030284A discloses and extracts carbon from human body or animal hair, then by carbon graphite, and then diamond growth at high temperature under high pressure.As shown in Figure 1, above several method comprises extraction carbon, the process of the high temperature graphitization of carbon, and graphite is the Growth of Single Crystal Diamond process under the HTHP of carbon source.
The present invention uses human body/animal hair, or other animals and plants organism is that raw material extracts solid carbon, by the HTHP production technology of uniqueness, grows the diamond of exclusive peculiar individuality.Thus impart the feature of diamond life, to the supplier of hair, there is special commemoration meaning.
Summary of the invention
For the above-mentioned problems in the prior art, technical problem to be solved by this invention is to provide one human body/animal hair, or other animals and plants organism is the method that life diamond prepared by raw material.
The present invention seeks to realize like this:
A preparation technology for life diamond, carries out as follows:
(1) in vacuum, reducing atmosphere or inert atmosphere, to human body or animal hair, the carbohydrate of all animals and plants parts carries out high-temperature process, therefrom extracts solid carbon;
(2) immerse in strong acid and highly basic to this solid carbon, remove impurity, carry out purification processes;
(3) to the solid carbon after purifying and metal solvent or nonmetal catalyst or without under catalyst condition, diamond fine powder or particle is generated at high temperature under high pressure;
(4) be raw material by the diamond fine powder of generation or particle, application temperature differential method (crystal seed method), grows Gem Grade bulky diamond monocrystalline at high temperature under high pressure;
(5) be life diamond by this Tabular gem-grade diamond cutting processing.
In above-mentioned steps 1, solid carbon major part is amorphous carbon.
In above-mentioned steps 3, synthesis pressure is greater than 6GPa, and temperature is greater than 1300 DEG C.
Beneficial effect: the solid carbon after the present invention utilizes purification directly generates bortz powder, then makes carbon source with bortz powder, rapid growth of diamond single-crystal.The method eliminates graphitizing process, is conducive to shortening the production cycle in production process and reducing costs.Meanwhile, with comparing by the method that graphite makes carbon source of having delivered, the present invention uses the mixture of bortz powder or bortz powder and graphite powder as carbon source, chamber pressure can be avoided to decline and problem on deformation, be conducive to the growth of high quality single crystal.
