已经开发了一种化学反应系统，该系统通过硅酸烷基酯的水解和随后的辛酸在醇溶液中的缩合，允许具有均匀尺寸的球形二氧化硅颗粒的受控生长。氨被用作形态催化剂。悬浮液中获得的粒径范围为直径小于0.05 μ至2 μ。
A system of chemical reactions has been developed which permits the controlled growth of spherical silica particles of uniform size by means of hydrolysis of alkyl silicates and subsequent condensation of silicic acid in alcoholic solutions. Ammonia is used as a morphological catalyst. Particle sizes obtained in suspension range from less than 0.05 μ to 2 μ in diameter.
