Abstract
Official abstract text for this publication.
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° C. or higher and lower than 300° 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° C.
First claim
Opening claim text (preview).
1 . 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 comprises spray-drying 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 in an atmosphere at 50° C. or higher and lower than 300° C.; and subsequently, firing the spray-dried product in air at 800 to 1,000° C. 2 . A forsterite microparticle production method according to claim 1 , wherein the colloidal silica has a primary particle size of 2 to 100 nm, as determined through electron microscopy. 3 . A forsterite microparticle production method according to claim 1 , wherein the water-soluble magnesium salt is an organic acid salt of magnesium. 4 . A forsterite microparticle production method according to claim 2 , wherein the water-soluble magnesium salt is an organic acid salt of magnesium. 5 . A forsterite microparticle production method according to claim 3 , wherein the magnesium organic acid salt is at least one species selected from the group consisting of magnesium citrate, magnesium glycolate, magnesium malate, magnesium tartrate, magnesium lactate, magnesium malonate, magnesium succinate, and magnesium acetate.
