Abstract
A method for coating the surface of inactive granules comprises dispersing inactive granules having water adsorbed in advance on the surface thereof in a solution having a higher fatty acid and a metal alkoxide dissolved in small amounts in a non-hydrophilic organic solvent thereby forming on the surface of the granules a dense layer of microfine metal oxide powder produced in consequence of hydrolysis of the metal alkoxide.
