2019/8/23· Other ways to process silicon carbide, demonstrated by the University of Texas (UT), include a hybrid powder bed-based approach which coines selective laser sintering and binder jetting. The process involves laser sintering a SiC powder mixed with binder compounds (green part), carbonization of the binder (brown part) and reactive infiltration of liquid silicon.

Silicon Carbide (SiC) | Morgan Technical Ceramics

Silicon carbide is formed in two ways, reaction bonding and sintering. Each forming method greatly affects the end microstructure. Reaction bonded SiC is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles.
