wholesale tibetan jewelry How does diamond make?

wholesale jewelry chain silver The technology of artificial synthesis diamonds is mainly to imitate the environment of natural diamond growth to cultivate diamonds. In terms of the growth method of crystal formation, synthetic diamonds can be roughly divided into three methods: one is the high temperature and high pressure method, the other is the vibration wave method, and the third is the syncope method of chemical gas.
I. High temperature and high pressure method: The materials used in this method include coal, coke, graphite, paraffin, sugar, etc.; there are reports that have been listed in more than 20 kinds of synthetic materials. The catalysts for applications can be used with iron, cobalt, nickel, 铑, 钌, 钯, 锇, 铱, chromium, magnesium, and magnesium, or these metal elements. It is required to reach at least 75,000ATM (atmospheric pressure). It is best to have a high pressure state of 80,000ATM to 110,000ATM. The formation temperature should be between 1200 ° C.12000 ° C. Essence The middle part of the reactor is a high temperature area, the carbon source is placed in the area, and the crystal species is placed in the low temperature zone of the lower part of the reactor. Taking graphite as the carbon source, the crystal species is fixed in the crystal bed of sodium chloride (salt). A special crystal of the crystal species faces the metal catalyst. The diameter of 6mm, 3mm thick, and the cylinder of the metal catalyst in the crystal species and carbon source. This metal catalyst is iron nickel alloys. After the combination, put into one -way pressure, four oblique sliding surface -style three -dimensional ultra -high -pressure high -temperature device, then put it in a oil compressor of 10,000 meters. Hour.
. The vibration wave method: It mainly uses the instantaneous high temperature and high pressure conditions generated during the explosion to synthesize diamonds. The synthetic diamond particles are small (commonly referred to as diamond powder), which is only suitable for industrial application.
. Chemical gas phase precipitation method: First of all, hydrogen and hydrocarbon -containing gases (generally used methane CH4), through a set of regulators, adjust the proportion of two gases, and then use microwave sources or electric heating wires to heat, heating, etc. The mixed gas makes the temperature of about 2000 ° C. Hydrogen and methane will be decomposed into a plasma flow formed by hydrogen atoms and carbon atoms, and then the tuberculosis will grow into a thin film on the substrate of heating to 600 ~ 1000 ° C.
