Abstract

Hydrous magnesium silicates having a crystal structure similar to that of natural hectorite may be produced by a precipitation process in which silica is precipitated into a preformed aqueous suspension of a water insoluble magnesium compound. The process may be operated at high concentration and the products may have good dispersibility in aqueous media and high optical clarity when dispersed as well as the good rheological properties which may be obtained by prior precipitation processes.
