溶胶-凝胶法合成堇青石的研究进展

Research advances of sol-gel technology based cordierite material synthesis

用溶胶-凝胶法合成的堇青石材料热膨胀系数、介电性低,化学稳定性高,广泛应用于电子器件、低温热辐射材料等高新技术领域。本文综述了工艺条件、元素掺杂对堇青石材料的合成与性能的影响,并对近期的研究热点进行了展望。

Sol-gel technology synthesized cordierite material has such positives as low thermal expansion coefficient, low dielectric properties and high chemical stability, so such material can be widely applied in electronic components and low-temperature thermal radiation materials. This paper surveys the influences of technological conditions and elements addition on the synthesis and properties of cordierite materials and presents the prospect of recent research focuses.
