Reaction Formed SiC Prepared by Room Temperature Freezing Casting

摘要：

　　The porous carbon preforms with fine pore structure has been successfully fabricated by room temperature freezing casting,and the reaction formed SiC with fine mechanical property has prepared successfully by liquid silicon infiltration process.Charcoal powder was used as carbon resource,camphene was used as sublimate vehicle,methyl cellulose was used as pore maker and bonder.The result shows that the homogeneity of the porous carbon preform has been improved largely by adding methyl cellulose,and the defects of reaction formed silicon carbide has reduced largely also.The density,average flexural strength and Weibull modulus of the best reaction formed silicon carbide prepared in this paper is 2.86 g/cm3,430.75MPa and 9.29 respectively.
