brief introduction of sintered silicon carbide

sintered silicon carbide (also known as atmospheric pressure sintering) is considered to be the most promising sintering method for SiC sintering. Complex shapes and large sizes of SiC components can be produced by the pressureless sintering process. According to the different sintering mechanisms, the pressureless sintering can be divided into solid-phase sintering and liquid-phase sintering. Solid-phase …
