聚碳硅烷低温烧结碳化硅泡沫陶瓷的制备

Preparation of Silicon Carbide Foam Ceramic at Low Temperature with PCS

采用聚碳硅烷(Polycarbosilane,PCS)陶瓷先驱体作为粘结剂,SiC微粉作骨料,在惰性气氛中1 000℃下低温烧结制备出碳化硅泡沫陶瓷。运用扫描电镜研究了固相含量、聚碳硅烷含量对碳化硅泡沫陶瓷的微观形貌的影响。

Silicon carbide foam ceramics were fabricated from SiC powders,polycarbosilane（PCS）at low temperature of 1000℃ in inert atmosphere. Microstructure were tested, results showed that the effect by PCS content.
