摘　　要：碳化硅陶瓷材料具有良好的耐磨性、导热性、抗氧化性及优异的高温力学性能,被广泛应用于能源环保、化工机械、半导体、国防军工等领域。然而,由于碳化硅为强共价键化合物,且具有低的扩散系数,导致其在制备过程中的主要问题之一是烧结致密化困难。因此,大量研究工作通过烧结技术的研究与烧结助剂的选择和优化等手段促进碳化硅致密化过程,降低烧结温度,细化晶粒,改善碳化硅陶瓷材料的各项性能。本文基于对碳化硅材料烧结行为、显微结构以及力学性能的认识,综述了碳化硅烧结工艺的发展及烧结助剂的选择标准,同时分析和介绍了碳化硅陶瓷材料在传统工业与现代科技领域的应用现状。Due to the favourable wear resistance,thermal conductivity,oxidation resistance and excellent high temperature mechanical properties,SiC ceramic materials are used in a wide range of fields such as energy and environmental protection,chemical machinery,semiconductor,national defense and military industry.However,densification has been one of the main problems for the preparation of SiC ceramic materials with high density resulting from the covalent bonding of silicon carbide and low diffusion coefficient.Therefore,extensive research works focus on the sintering technology and the selection and optimization of sintering aids to promote the densification process of silicon carbide,reduce the sintering temperature,refine the grains,and improve the performance of silicon carbide ceramic materials.Based on understanding about sintering behavior,microstructure and mechanical properties of SiC materials,the progresses made in sintering of SiC ceramics and the selection standard of sintering aids were summarized in this paper.The application status of SiC ceramic materials in traditional industry and modern science and technology have also been introduced.
