高温气静压是粉末冶金中日益发展的方法之一。根据资料,用高温气静压制取的产品总额,在1983年是十亿元,到1993年将达到六十亿元。难熔化合物,其中如氮化物,用气体进行高压处理是特别有前途。难熔化合物进行高温气静压需要有高温(1800℃或更高)气静压设备,这是在工业上应用这个方法制取氮化物陶瓷受到限制的一个原因。到1984年末,全世界已采用了350台气静压装置,其中大部分工作温度低于
High temperature hydrostatic pressure is one of the growing methods in powder metallurgy. According to the information, the total amount of products made by high-temperature static pressure was 1 billion yuan in 1983 and will reach 6 billion yuan by 1993. Refractory compounds, such as nitrides, with high pressure gas treatment is particularly promising. Refractory compounds for high temperature hydrostatic pressure require high temperature (1800 ℃ or higher) static pressure equipment, which is the industrial application of this method nitride ceramics is limited to one of the reasons. By the end of 1984, 350 aerostatic devices had been installed worldwide, most of them operating below temperatures
