Ferroelectric ceramics

Ceramics technology is more an art than a science, due to the complexity of chemical systems involved. Even with simple bodies there are major constituents which form solid solutions, mixtures and glassy phases. The major constituents bring in impurities which also form solid solutions, mixtures and glasses; therefore, it is not surprising that the combinations often become too complex for scientific solution. When raw material, processing, firing and finishing variables are considered, we can see that intuition plays a greater part than in many industries.
