一、前言钼熔点高(2620℃),高温下具有良好的机械性能。在照明、电子机械等零部件及各种加热炉用材料方面得到广泛应用。近来对各种用途的钼在高温高强度方面提出了更高的要求。例如,半导体的陶瓷基板,核燃料UO_2及OA机的小型电机用稀土磁性材料的烧结用舟皿和垫板,要求钼材在 First, the preface Molybdenum melting point (2620 ℃), high temperature has good mechanical properties. In the lighting, electronic machinery and other components and a variety of furnace materials have been widely used. Recently, various applications of molybdenum in the high temperature and high strength put forward higher requirements. For example, ceramic substrates for semiconductors, boats and plates for sintering of rare-earth magnetic materials for small motors such as nuclear fuel UO 2 and OA machines,
