一、多晶莫来石纤维发展概况耐高温陶瓷纤维以其低热容、低导热性、耐温度冲击和低的容重作为优质保温和绝热材料而应用于工业加热设备。在国内外,耐高温陶瓷纤维这种节能型的材料的研制与发展都很快。其中硅酸铝纤维(简称C F),在我国于1979年开始形成生产力并供应国内市场。1981年在洛阳会议上我国将C F材料列为重点推广的节能新材料。CF在1000℃以下热处理炉上应用得到的效益已被公认。但C F在1000℃以上的条件下应用时在较短时间内即产生纤维结构损毁、粉化、脱落。人们在研究C F损毁机理时无疑注意到其矿相组成。作者于1983年5月即发表了“Al_2O_3-SiO_2系多晶质纤维高温下结构变化”的论文,并在浙江德清晶体纤维
First, the development of polycrystalline mullite fiber High temperature resistant ceramic fiber with its low heat capacity, low thermal conductivity, temperature resistance and low bulk density as a high-quality insulation and insulation materials used in industrial heating equipment. At home and abroad, the development and development of energy-saving ceramic materials such as high temperature resistant ceramic fiber are fast. One aluminum silicate fiber (referred to as C F), in our country in 1979 to form a productive force and supply the domestic market. At the Luoyang Conference in 1981, China listed CF as the key energy-saving new material. The benefits of using CF at heat treatment furnace below 1000 ℃ have been recognized. However, the application of C F under the condition of 1000 ° C or above results in the fiber structure being damaged, pulverized and shedding in a relatively short period of time. People are undoubtedly aware of the mineralogical composition when studying the mechanism of C F damage. The author published in May 1983 that “Al 2 O 3 -SiO 2 polycrystalline fibers structural changes at high temperature,” the paper, and in Zhejiang Deqing crystal fiber
