作为常用结构材料和耐热材料使用的金属和陶瓷等材料,通过特殊的形态变化可以改变性能而制成具有优异的热工、电工和化学性能的功能材料。这种功能材料已成为当前新材料研制开发的重点之一而倍受重视。在金属、陶瓷、高分子材料等新型功能材料的研制开发中,超微粒的设计和制备等微粒化技术至关重要,而且发展较快。 Materials such as metals and ceramics, which are commonly used as structural materials and heat-resisting materials, can be changed into functional materials with excellent thermal, electrical and chemical properties through special morphological changes. This functional material has become the focus of research and development of new materials. In the research and development of new functional materials such as metals, ceramics and macromolecular materials, the microparticulation technology such as the design and preparation of ultrafine particles is crucial and has developed rapidly.
