Abstract

Sintered bodies containing at least 90 per cent barium titanate are heated to sintering temperature and then cooled to 900 DEG C., the total time the bodies are above 900 DEG C. not exceeding 3 hours. The process is particularly applicable to compositions described in Specification 586,802 but in examples, additions to the barium titanate include bentonite, magnesium fluoride, zinc oxide, boric acid, magnesium zirconate, and magnesium titanate. Bodies treated by prior heat methods benefit from the process.
