high quality large size cvd diamond for diamond tools

A review of diamond synthesis by CVD processes -

Oct 01, 2011 · Since the middle of the 1950s, the interest in diamond increased with the possibility of growing carbon by using a wide variety of chemical vapor deposition (CVD) techniques. These techniques allow the deposition of four different types of carbon:amorphous carbon with sp 2 -bonded atoms (a-C), tetrahedral bonded amorphous carbon (ta-C), polycrystalline and monocrystalline diamonds
