Special discount for this B grade quality cvd diamond seeds or cvd scalpel blade or cvd diamond cutter.
Size: 7*7 8*8 9*9
Thickness:0.3-0.5mm
Quality: Rough. both side unpolished.
With small polycrystalline spot,and small crack on the side.
In hands for 2000CT. as picture .Sold by carat.
One carat 2-3pcs.
CVD single crystal diamond properties:
Since CVD diamond does not contain any metal catalysts, its thermal stability is close to that of natural diamond. Like high temperature and high pressure artificially synthesized polycrystalline diamond, CVD diamond grains are also arranged in disorder, without brittle cleavage planes, so they are isotropic.
nitrogen content：<50ppm
Hardness (microhardness)：80～150GPa
Young's modulus：1150～130OGPa
coefficient of friction：0.05~0.05
