Method for manufacturing high-performance aluminum oxide/nano silicon carbide composite ceramic
A method for manufacturing high-performance aluminum oxide/nano silicon carbide composite ceramic is characterized in that bauxite powder and nano SiC particles are adopted as main raw materials, wet mixing, drying and precalcination are carried out, then bury-burning is carried out after forming, sintering is carried out at the temperature of 1,400 DEG C to 1,550 DEG C, heat preservation is carried out for one hour, then natural cooling is carried out to room temperature, and the high-performance aluminum oxide/nano silicon carbide composite ceramic is manufactured. According to the manufactured composite ceramic, the nano SiC particles are distributed in an aluminum oxide base in situ, a little mullite exists, the method is simple in manufacturing process, and the manufactured composite ceramic has the high cost performance.
