1、 Definition and Characteristics
Semiconductor ceramics are innovative materials that combine semiconductor properties with ceramic morphology. It not only inherits the high hardness, excellent heat and corrosion resistance of ceramics, but also combines the excellent electrical properties of semiconductor materials, such as good conductivity, specific resistivity, and a certain dielectric constant.
2、 Preparation method
There are two main methods for preparing semiconductor ceramics. Firstly, using chemical vapor deposition (CVD) technology, semiconductor materials are deposited on a ceramic substrate to form ceramic composite materials; Secondly, first produce semiconductor ceramic powder, and then process it into ceramic products using sintering and other techniques.
