Technology & Materials - Paxis Ceramics

Reaction bonded silicon carbide (RBSC) is produced from a finely divided mixture of silicon carbide and carbon. The silicon reacts with the carbon to form additional silicon carbide, bonding the particles together. Silicon also fills the residual open pores. RBSC undergoes minimal dimensional change during sintering (less than 0.1%).
