HIGH-PURITY BARIUM CARBONATE

ホーム > HOME > Research and Development > Introduction on technology > HIGH-PURITY BARIUM CARBONATE

Overview

Barium carbonate was previously used in barium glass (such as in cathode ray tubes) and barium ferrite, but the high purity barium carbonate is now used widely as ingredients of electronic materials.
The applications include ingredients of barium titanate, used in ceramic capacitor (MLCC), compound oxides, or PTC thermistors.
Also, it is used for optic glass and sputter glass for semiconductors, and for barium components in fluorescent materials.
