What's the synthetic diamond
Synthetic Diamond are diamonds manufactured in a laboratory, as opposed to diamonds mined from the Earth. The gemological and industrial uses of diamond have created a large demand for rough stones. This demand has been satisfied in large part by synthetic diamonds, which have been manufactured by various processes for more than half a century. However, in recent years it has become possible to produce gem-quality synthetic diamonds of significant size,synthetic diamond rough HPHT diamond cvd diamond manufacturers in China
A popular method of growing synthetic diamnd is chemical vapor deposition(CVD). The growth occurs under low pressure(below atmospheric pressure). It involves feeding a mixture of gases(typically 1 to 99 methane to hydrogen) into a chamver and splitting them to chemically active radicals in a plasma ignited by microwaves, hot filament, arcdischarge, welding torch or laser. This method is mostly used for coatings, but can also produce single crystals several millimeters in size.
