现代,超高温真空电阻炉的加热器、隔热屏及其元件,都是用稀有的和昂贵的钨、钼材料。因为,根据超高温真空电阻炉生产的情况,在电热设备中,估计这种炉子的发展是比较快的(当前的情况)。在今后,消耗这类金属还会显著增加。由于这些情况,出现了人们感兴趣的材料。其中,有用碳化铌代替钨、钼材料。 至今,因为这些材料是用粉末冶金方法生
Modern, ultra-high temperature vacuum resistance furnace heaters, heat shields and their components, are rare and expensive tungsten, molybdenum materials. Because, according to the production of ultra-high temperature vacuum resistance furnace in the electric equipment, it is estimated that the development of this furnace is relatively fast (the current situation). In the future, consumption of such metals will also increase significantly. Due to these circumstances, material of interest has emerged. Among them, useful niobium carbide instead of tungsten, molybdenum materials. So far, because these materials are produced by powder metallurgy
