Abstract
To provide a method for producing inorganic oxide hollow particles having excellent water resistance.SOLUTION: A method for producing water-resistant inorganic oxide hollow particles comprises: a first step of heating inorganic oxide hollow particles at a temperature within a range of -500°C±100°C relative to a melting point of the hollow particles; and a second step of slowly cooling the heated inorganic oxide hollow particles up to a temperature of 1 / 2±100°C of the heating temperature at an average cooling rate of 1°C / min or more and 28°C / min or less.SELECTED DRAWING: None
