摘要
A solid-phase method for making a barium titanate powder involves the steps of compounding powdered barium carbonate and powdered titanium oxide and calcining the mixture. The powdered barium carbonate used is needle particles having an aspect ratio of the length of the long axis to the length of the short axis of at least about 2. The powdered barium carbonate preferably has a specific surface area of about 5 m2/g or more. The resulting barium titanate powder is finer and homogeneous.
