通过溶胶-凝胶过程对材料的超微结构控制为实现玻璃、玻璃陶瓷、陶瓷和复合材料的可靠性能提供了重要前景。只有了解溶胶-凝胶过程的基本化学原理才能实现这一点。将针对光学玻璃、结构陶瓷和电磁材料介绍基于此方法的几个示例。将讨论陶瓷或玻璃分子复合材料和光学活性凝胶等新概念。将展示这些新概念是如何从对聚合物化学和化学反应性的理解中衍生出来的。讨论先进的溶胶-凝胶基础研究方向及其前景。
The ultrastructural control of materials through sol-gel processes offers significant promise for the achievement of reliable performance in glass, glass-ceramics, ceramics and composites. This will be attainable only if the fundamental chemistry of the sol-gel process is understood. Several examples based on this approach will be presented for optical glass, structural ceramics and electromagnetic materials. New concepts, such as ceramic or glass molecular composites and optically active gels, will be discussed. It will be shown how these new concepts are derived from an understanding of polymer chemistry and chemical reactivity. Advanced sol-gel basic research directions and their prospects will be discussed.
