首先介绍了碳纳米管(CNTs)增韧氧化铝陶瓷的重要意义以及所面临的两个重大问题:CNTs在氧化铝基质中的均匀分散和CNTs与氧化铝基质较弱的界面结合。重点介绍了胶溶法、溶胶-凝胶法和原位合成法制备CNTsAl2O3复合材料的方法以及各自特点,简单介绍了水热晶化法以及其他的制备方法。 Firstly, the importance of toughening alumina ceramics with carbon nanotubes (CNTs) and the two major problems that they face are: uniform dispersion of CNTs in alumina matrix and weak interface between CNTs and alumina matrix. The methods of peptization, sol-gel and in-situ synthesis of CNTsAl2O3 composites were introduced emphatically, and their respective characteristics were briefly introduced. Hydrothermal crystallization and other preparation methods were briefly introduced.
