摘　　要：介绍了陶瓷及其复合材料(如:氧化物陶瓷、生物陶瓷、电子陶瓷、微波绝缘复合陶瓷、电池材料和sialon陶瓷复合材料)合成的机械力化学效应研究的进展。软机械力化学合成方法的生产成本低,将该方法用于工业化生产各种陶瓷材料具有相当大的应用前景。通过选择合适的原料和研磨条件,机械力化学合成的方法可用于制备很多高性能无机材料。用机械力化学合成的方法可加速并简化合成反应,减少能量和原材料的消耗,即经济又环保。同时,机械力化学合成的方法可以通过非常规的途径使纳米结构陶瓷材料晶化反应快速进行。针对此研究领域将来的发展方向提出了建议。This paper reviews recent developments on mechano-chemical synthesis of various ceramic materials and compositions (such as oxide ceramics, biomaterial ceramics, electronic and electric intermetallics, microwave dielectric composite, battery compounds, and sialon ceramic composites). The method of soft mechano-chemical synthesis has a considerable potential for low cost, large scale production of various ceramic materials. The technique can be extended to the synthesis of a very wide range of various powders of advanced inorganic materials by the suitable selection of starting materials and milling conditions. The method accelerates and simplifies the process of the synthesis, decreases the energy expenses and the cost of the materials, thus being more economically efficient and ecologically clean. The mechano-chemical procedure permits an unique preparative flexibility allowing for rapid solid-phase crystallisation of nano-structured ceramic materials. Further studies in this aspect are also proposed.
