PRODUCTION METHOD OF BARIUM TITANATE COATED WITH HIGHLY CRYSTALLINE SILICON DIOXIDE, AND BARIUM TITANATE POWDER COATED WITH HIGHLY CRYSTALLINE SILICON DIOXIDE PRODUCED BY THE METHOD
PRODUCTION METHOD OF BARIUM TITANATE COATED WITH HIGHLY CRYSTALLINE SILICON DIOXIDE, AND BARIUM TITANATE POWDER COATED WITH HIGHLY CRYSTALLINE SILICON DIOXIDE PRODUCED BY THE METHOD
PROBLEM TO BE SOLVED: To provide a production method of barium titanate coated with highly crystalline silicon dioxide (SiO), and a barium titanate powder coated with highly crystalline silicon dioxide (SiO) produced by the above method.SOLUTION: The production method of barium titanate coated with highly crystalline silicon dioxide (SiO) includes steps of: preparing a barium hydroxide raw material after addition of a substance containing silicon (Si) and heating to ionize barium (Ba); preparing a titanium (Ti) raw material dispersed in an acid or a base; mixing the barium hydroxide raw material with the titanium raw material to react to obtain barium titanate seeds; mixing the barium titanate seeds with pure water and a grain growth inhibitor and growing grains; and coating surfaces of the barium titanate seeds grown into grains with silicon dioxide (SiO).
