真空烧结早已是一种处理含钛、钨、钽铌甚至是含稀土金属的复杂碳化物的方法。在大量的试验中,人们试图选择确保最终产品质量的最优烧结条件。烧结不是一种简单的现象。而是同时存在且互相制约的若干种现象的组合. 在大多情况下,烧结过程的开给阶段方提仔细地脱掉成型剂·这是因为大多数成型剂含 Vacuum sintering has long been a method of treating complex carbides containing titanium, tungsten, tantalum, niobium and even rare earth metals. In a great deal of experimentation, people are trying to choose the optimal sintering conditions that will ensure the quality of the final product. Sintering is not a simple phenomenon. But rather a combination of several phenomena which exist simultaneously and are mutually restrained, and in most cases the opening phase of the sintering process is careful to remove the forming agent because most of the forming agent
