补充资料:碳化钼陶瓷
分子式:
CAS号:

性质:钼与碳的化合物为主要成分的陶瓷。主要有两类。(1)以碳化二钼(Mo2C)为主晶相的陶瓷。呈暗灰色。理论密度9.2g/cm3。熔点2690℃。莫氏硬度7。显微硬度1800kg/mm3(负荷50g)。弹性模量22100kg/mm2。热导率6.7×106W/(m·K)。2300℃以上分解。(2)以一碳化一钼(MoC)为主晶相的陶瓷。理论密度8.88g/cm3。熔点2700℃。一般先制成碳化钼粉末(采用钼与碳直接化合法、金属氧化物与碳的还原一化合法、气相沉积法和自蔓延高温合成法),然后在真空或还原气氛下在碳管炉、钼丝炉、高频真空炉中进行烧结(多采用反应烧结、热压烧结和热等静压烧结)而制成。主要用作超硬工具材料、耐磨材料、发热体材料以及高温结构材料。
