美国Imperial Chemical Industrics开发了一种Saffil氧化铝纤维。他们采用一种监控式分解制造工艺,生产出的氧化铝纤维含量达96～97%,其多晶纤维结构在α相稳定,添加3～4%的二氧化硅添加剂,作为晶粒长大的抑制因子。在真空高温绝缘装置里,该材与高纯难熔粘接剂混合,使高Saffil的直径稳定性得到增强,并提高了
Imperial Chemical Industries of the United States has developed a Saffil alumina fiber. They employ a controlled decomposition process to produce 96-97% alumina fibers with a stable polycrystalline fiber structure in the α phase with 3-4% silica additives added as grain growth Inhibitors. In vacuum high temperature insulation, the material is mixed with a high-purity refractory binder to increase the diameter stability of high Saffil and increase
