SML Shaped CVD Diamond Lab Grown Diamond Wafer Plate Rough 

 

CVD synthetic diamond is an acronym for chemical vapor deposition diamond, pure diamond polycrystalline structure, no cutting surface, no metal binder.The newer method, chemical vapor deposition (CVD), involves filling a vacuum chamber with carbon-containing gas that crystallizes on a synthetic diamond seed. This method uses lower temperatures and pressures than HPHT. Both methods are currently popular methods of diamond growth. The CVD diamond growth method requires a lower upfront equipment cost than HPHT but may require subsequent treatment to improve the color of the diamonds grown.

 

Diamond seed crystals are placed in a diamond growth chamber

 

The chamber is filled with carbon-containing gas.

 

The chamber is heated to about 900-1200°C.

 

A microwave beam causes carbon to precipitate out of a plasma cloud and deposit onto a seed crystal. 

 

Diamonds are removed every few days to have the top surface polished to remove any non-diamond carbon before being put back in to grow. Each batch of diamonds may require several stop/start cycles, and the entire growth process can take three or four weeks.After the synthetic diamond crystals are removed, they are ready to be cut and polished into the final product.
