以ZrB2、碳化硅和碳纳米管为原料，在1900℃、30 Mpa下热压1h，制备了不添加和添加2wt%碳纳米管(CNTs)的ZrB2-20体积%碳化硅陶瓷。碳纳米管的加入使复合材料的断裂韧性提高了约15%，但硬度、抗弯强度和导热系数变化不大。(C)2007 Elsevier B.V.保留所有权利。
ZrB2-20 vol%SiC ceramics without and with additive of 2 wt% carbon nanotubes (CNTs) were fabricated by hot-pressing at 1900 degrees C for 1 h under 30 MPa using ZrB2, SiC and CNTs as starting materials. The fracture toughness increased about 15%, but hardness, flexural strength as well as thermal conductivity did not vary significantly from the addition of CNTs. (c) 2007 Elsevier B.V.
