仿生SiC陶瓷材料的制备和性能

摘要

Biomorphic SiC ceramics are novel environmentally friendly materials. Due to their excellent properties such as low density, high mechanical strength, resistance on corrosion, friction and oxidation, absorbability and hioactivity, biomorphic SiC ceramics are promising materials which could be used in the fields of mechanics, chem- ical industry, catalysis and bio -medicine. This article summarizes the different fabrication techniques of the bio- morphic SiC ceramics and their mechanical, thermal and electrical properties, as well as their biological compati- bility. The analysis has been done for the existing problems, and the outlook for the development trends.%仿生SiC陶瓷材料是一种新兴的环境友好材料，因其具有密度低、强度高、耐腐蚀、耐磨损、抗氧化和生物相容性好等优点，在机械、化工、催化、生物医学等领域都有着广阔的应用前景。就仿生SiC陶瓷材料的多种制备工艺和其机械性能、热性能、电性能、生物相容性等进行了综述，并对其存在的问题进行了分析，对其发展趋势进行了展望。
