通过高能球磨实现的超细粉碎过程使固体颗粒晶粒细化,产生微裂纹、晶格畸变、表面能升高、反应能力增强,从而实现低温化学反应,称为机械力化学。此法开辟了制备材料的新途径,因而得到广泛重视。本文综述了机械力化学的概念及作用机理。阐述了机械力化学在制备纳米陶瓷材料及纳米复合材料中的应用。介绍了机械力化学法的发展现状及其优缺点。 The ultrafine grinding process achieved by high-energy ball milling makes the grain refinement of solid particles, resulting in microcracks, lattice distortion, surface energy increases, the reaction ability to enhance, in order to achieve low temperature chemical reactions, known as mechanochemical chemistry. This method has opened up new ways of preparing materials and has gained wide attention. This paper summarizes the concept and mechanism of mechanochemistry. The application of mechanochemistry in the preparation of nano-ceramic materials and nano-composite materials is expounded. The development status and advantages and disadvantages of mechanochemical method are introduced.
