摘要：

Sintering additives were prepared from aluminum hydroxide and yttrium hydroxide. These additives were soluble in water and resulted in a binder. A β-SiC powder was mixed with the additive solution and sintered at 2150°C without pressure. The oxides formed from the additive promoted sintering. The sintered body contained no pores. Aluminum, silicon, and yttrium oxide were precipitated in the sintered body.
