What is the basic principle of the way to semiconductorize functional ceramics?

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:

What is the basic principle of the way to semiconductorize functional ceramics

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.
