先驱体转化法原位制备功能梯度陶瓷

Polymer Precursor Route for In Situ Preparation of Functional Gradient Ceramics

探索性地采用一种陶瓷制备方法——先驱体转化法原位制备功能梯度陶瓷,样品测试结果表明,材料具有电阻梯度特性以及微波段吸收电磁波特性。

A kind of preparation method for ceramics,polymer precursor route was utilized to prepare func- tional gradient ceramics,and the results showed that,for these ceramics,conductivity decreases gradually from the up- per surface to the lower surface of ceramics,with a good attenuation profile over a broad microwave band.
