科学技术的发展,在很多场合,要求在高温下使用的材料具有稳定性和可靠性,因此,材料在高温下挥发的问题,引起了冶金、耐火材料、能源和电子材料等部门的材料科学工作者的重视。一、测定材料高温挥发的方法各种材料(纯物质、固溶体、化合物或机械混合物)在高温下挥发的速度不同,其测量 The development of science and technology requires, on many occasions, the stability and reliability of materials used at high temperatures. Therefore, the problem of material volatilization at high temperatures has led to material science work in such sectors as metallurgy, refractory materials, energy and electronic materials People’s attention. First, the method of determination of high temperature volatile materials Various materials (pure matter, solid solution, compound or mechanical mixture) volatile at different temperatures at different rates, the measurement
