CVD diamond seeds
Chenguang
CVD diamond (also known as Synthetic diamond, Chemical vapor deposition diamond, laboratory-grown diamond, laboratory -created diamond )is diamond produced in an artificial process, as opposed to natural diamonds, which are created by geological processes.
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
Thermal expansion coefficient：10-.K-l
Thermal conductivity：1500-2000 w/ (m·K)
Clearance diamond plates:
Size: 7*7 8*8 9*9 10*10
Thickness:0.3-0.5mm
Quality: Rough unpolished, single side polished, double-side polished, with a little of defects: polycrystalline spot, a small cracks on the edge
Special discount for this B grade quality cvd diamond seeds or cvd scalpel blade or cvd diamond cutter.
Ordinary CVD plates size Available:
| Suggested application | Sustrated/seeds for single crystal CVD growth |
