凝胶注模成型制备SiAlON-SiC复相材料

STUDY ON SiC-SiALON COMPOSITE MATERIAL BY GELCASTING

以Al、Si、SiO2和SiC为原料,采用凝胶注模成型及氮气气氛下烧成的方法制备了SiAlON-SiC复相材料。对浆料的流变特性、坯体的性能及制品烧结性能进行了研究。

SiAlON -SiC composite material has been prepared by gelcasting and by sintering in N2 with Al, Si, SiO2 and SiC as raw materials,whose rheological behavior,body and sintering properities have been studied.
