Title:
チタン酸ストロンチウム微粒子粉末及びその製造方法
Document Type and Number:
Japanese Patent JP6583637
Kind Code:
B2
Abstract:
The present invention relates to a strontium titanate fine particle powder that is a cubic strontium titanate and is characterized in that the average primary particle size of primary particles is 50-150 nm and the sphericity is at least 0.8. Said cubic strontium titanate can be obtained by heating a hydrated titanium hydroxide slurry obtained by neutralizing a titanium tetrachloride aqueous solution in a hydrated strontium aqueous solution, then adding the hydrated strontium aqueous solution and inducing a wet reaction at a temperature range of 60-200 °C. This spherical strontium titanate fine particle powder has excellent dispersibility.
