Properties of h-BN/Si3N4 Composite Ceramics Fabricated by Gel-Casting

摘要：

　　h-BN/Si3N4 composite ceramics were fabricated by gel-casting method and pressureless sintering using Si3N4 and h-BN as raw materials.The effect of h-BN on the microstructure and comprehensive properties of h-BN/Si3N4 ceramic were investigated.The results showed that the introduction of h-BN hindered the densification of h-BN/Si3N4 ceramic as well as the transformation of α-Si3N4 to β-Si3N4.The mechanical properties of Si3N4 based ceramics decreased with the increase of h-BN content,while the thermal property,dielectric properties and machinability increased.
