It is achieved in an environment of high temperature and super-high pressure and thermally stable up to 1,200°C for its insert binder (mainly Si). Its Sic has a similar coefficient of thermal expansion to that of diamond & enjoys very good wear-resistance.

2)Applications

Different thermally stable polycrystalline diamond products with different performances of wear-resistance, toughness, self-sharpening & high-temperature resistance can be used in gem-processing, Sic wheel dressers, wire drawing dies, coated cutters, etc. It can be applied on the  drilling bits for oilfields.
