CVD series

Diamonds have many excellent properties; in addition to their resistance, their hardness (hardness), Mohr-density (molardensity), thermal conductivity rate, speed of sound and elastic modulus are the highest among known substances; other excellent features include negative electron affinity (negative electron affinity, NEA), low friction coefficient, high refractive index, low thermal expansion coefficient, far-infrared light to X-ray range of optical penetration, good electrical insulation, width of the valence band, the high rate of electron-hole mobility, etc.

Solid deposition films can form by gaseous substance chemical reaction in solid surface. It’s the deposition technologies, which using thermal energy pressed with thermal decomposition and combination at high temperature.
