摘要:堇青石具有低的热膨胀系数、较好的抗热震性能等优点,广泛应用于耐火材料,电子封装材料,多孔陶瓷,催化剂载体及红外辐射材料.目前,工业上主要通过人工合成的方法制备堇青石.人工合成堇青石所用原料已在天然矿物原料的基础上,扩大到固体废物等原料,并且已有很多成功的合成实例.与天然产出的堇青石相比,合成堇青石的性能更加优越.从堇青石的合成原料、合成方法及机理、添加剂改性等方面,就其研究进展进行了介绍,并认为加强对其他合成方法及低温合成的研究,加强对改性添加剂及从固体废物中寻找原料的研究是未来的发展趋势.

Abstract:Cordierite has a low coefficient of thermal expansion, good thermal shock resistance, etc., and is widely used in refractory materials, electronic packaging materials, ceramics, catalyst carriers and infrared radiation materials. Currently, it is mainly made by artificial synthesis in industry. Synthetic cordierite materials are expanded from natural minerals to solid waste materials, and there are many successful synthesis examples. Comparing with naturally occurring cordierite, synthetic cordierite has superior performance. In this paper, the research progress such as raw materials, the methods and mechanism, and additives modified are introduced. It would be concluded that the future development is to strengthen those researches on low- temperature synthesis, modified additives and look for the raw materials from solid waste.
