METHOD FOR PRODUCING FORSTERITE FINE PARTICLE
PROBLEM TO BE SOLVED: To provide a method for producing the fine particles of forsterite in which a production method is simple, and also usable as an insulation material for an electronic small part.SOLUTION: Provided is a method for producing forsterite fine particles obtained by atomizing and drying a solution containing a water-soluble magnesium salt and colloidal silica by the molar ratio of (Mg/Si)2 between magnesium atoms and silicon atoms at a temperature more than 50°C to below 300°C and thereafter firing the same at a temperature of 800 to 1,000°C in the air, in which the particle primary particle diameter by electron microscope observation lies in the range of 1 to 200 nm.
【課題】 製造方法が簡便であり、且つ電子分品用の絶縁材料として使用可能なフォルステライトの微粒子の製造方法を提供すること。【解決手段】 水溶性マグネシウム塩及びコロイダルシリカをマグネシウム原子とケイ素原子とのモル比(Mg/Si)2で含有する溶液を50℃以上300℃未満の温度で噴霧乾燥し、その後大気中で800乃至1000℃の温度で焼成することを特徴とする電子顕微鏡観察による一次粒子径が1乃至200nmの範囲のフォルステライト微粒子の製造方法による。【選択図】なし
