What is the basic principle of the way to semiconductorize functional ceramics? What are the factors that affect semiconductorization?
The way to semiconductor:
- 1. Donor doping semiconducting, generally high-valent doping La3+, Y3+, Sb3+, Nb5+, Ta5+
Fundamental: - 2. Forced reduction semiconductorization. Basic principle:
Factors affecting semiconductorization:
- (1) Influence of additives and impurities. If the concentration is too large or too small, the resistivity will increase and an insulator will be formed.
- (2) The influence of deviation of stoichiometric ratio. 3. The influence of firing conditions. The influence of firing temperature and holding time is greater.
