Sic Ceramic Ball
The density of Sic Ceramic Ball is 3.2g/cm3 and it’s the same as Si3N4 ball, at 1400℃, the intension and rigidity almost couldn’t be changed. Sic Ceramic Ball has the self-lubrication that can solve the pollution of lubricate medium. Comparing with Si3N4, Sic Ceramic Ball has higher rigidity, lower anti-press strength and lower rupture toughness.
