A method for producing forsterite microparticles having a primary particle size of 1, to 50 nm, as determined through electron microscopy. The method includes spray-drying, in an atmosphere of 50&#xb0; C. or higher and lower than 300&#xb0; C., a solution containing a water-soluble magnesium salt and colloidal silica at a mole ratio of magnesium atoms to silicon atoms (Mg/Si) of 2; and subsequently, firing the spray-dried product in air at 800 to 1,000&#xb0; C.

Production method for forsterite fine particles

A method for producing forsterite microparticles having a primary particle size of 1 to 200 nm, as determined through electron microscopy, characterized in that the method includes spray-drying, at 50&#xb0; C. or higher and lower than 300&#xb0; C., a solution containing a water-soluble magnesium salt and colloidal silica at a mole ratio of magnesium atoms to silicon atoms (Mg/Si) of 2; and subsequently, firing the spray-dried product in air at 800 to 1,000&#xb0; C.
