A method to produce barium titanate powder from pyrogenic titanium dioxide

摘要

A method to produce a barium titanate powder having a BET surface area of 10 to 25 m 2 /g comprising
- mixing a barium carbonate powder having a BET surface area of 20 to 50 m 2 /g and a pyrogenic titanium oxide powder having a BET surface area of 40 to 150 m 2 /g in a ratio to form a powder mixture
- milling the powder mixture,
- calcining the powder mixture in a temperature range from 700°C to 800°C.
