Uses: Necessary raw material for high purity of barium salts. To produce ceramic PTCR (Positive Temperature Coefficient resistance), high-precision NTC thermistor, ceramic capacitor, temperature sensor, electronic clinical thermometer, overvoltage protection precision electronic apparatus, high/low frequency capacitance, SMD(surface mount device) pressure sensitive ceramics, processing MOS (metal oxide semiconductor)chip, semiconductor elements, mono/multilayer chip varistor, Suppressor, MLCC(COG,Y5V,X7R)-Multilayer Ceramic Capacitors, radiation&heat prevention product etc. Also used in the production of barium titanate by the oxalate process, in the production of special glass and in the preparation of pharmaceutical intermediates.
