METHOD FOR MANUFACTURING HOLLOW PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing oxide hollow particles having improved particle diameter and/or shell thickness.SOLUTION: A method for manufacturing oxide hollow particles having an average particle diameter of 0.5-100 μm as measured by a spray pyrolysis method includes: a step of preparing a solution containing oxide constituting elements and an organic thickener; a drying step of removing a solvent from spray droplets of the solution; and a step of thermally decomposing dried particles to form oxide hollow particles.SELECTED DRAWING: None
