中文摘要:
      堇青石是一种具有较低热膨胀系数、良好抗热震性的矿物材料。天然的堇青石矿物原料很少,因此常常采用人工合成的方法来合成堇青石材料。本文根据近年来合成堇青石的最新研究,论述了堇青石合成方法的研究进展,具体包括高纯氧化物高温固相反应合成法、天然矿物高温固相反应合成法、利用工业废料合成法、利用农业废料合成法、溶胶-凝胶法和低温燃烧合成法。目前工业化生产堇青石大多采用天然矿物高温固相反应法,此法虽有众多优点,但同时也存在许多的不足之处。因此,如何能将其他方法用于工业化生产,将成为合成堇青石今后研究中的一个发展方向。
英文摘要:
      Cordierite is a mineral material characterized by low thermal expansion coefficient and good thermal shock resistance. Cordierite mineral material is relatively rare in nature, so cordierite is synthesized usually by the method of artificial synthesis. Based on the newest investigation results of synthetic cordierite, this paper deals with the progress of researches on such synthesis methods of cordierite as high purity oxide solid reaction at high temperature, natural mineral solid reaction at high temperature, the utilization of industrial wasted materials, the employment of agricultural wasted materials, the sol-gel and the low-temperature combustion synthesis. At present, the method of natural mineral solid reaction at high temperature is used for the preparation of cordierite in industry. In spite of a lot of advantages, this method also has many disadvantages. Therefore, the development trend of cordierite synthesis seems to solve the problem as to how to apply other synthesis methods to industrial preparation.
