Method of producing strontium titanate fine particles having cubic shape, cubic shape strontium titanate fine particles, cube shaped metal-doped strontium titanate fine particles, and method of producing the same
PROBLEM TO BE SOLVED: To provide strontium titanate fine particles having a cubic shape at a liquid phase under the atmospheric pressure at high productivity, a method for producing strontium titanate fine particles having a cubic shape and capable of producing rhodium(Rh)-doped strontium titanate fine particles, strontium fine particles having a cubic shape, and rhodium(Rh)-doped strontium titanate fine particles having a cubic shape.SOLUTION: A reaction liquid obtained by adding a strontium raw material, an anatase type titanate raw material and a rhodium salt into an alkaline aqueous solution is prepared, and the reaction liquid is heated at 90°C or more and at the boiling point or less under the atmospheric pressure, and the reaction liquid is made to be reacted.SELECTED DRAWING: Figure 1
