A process for producing a clay mineral of chain structure such as sepiolite and attapulgite. The process comprises suspending a metal silicate gel in an aqueous solution which has a pH value of 3-11 at room temperature and contains a clay mineral of chain structure suspending therein, and then heating the resulting suspension at a temperature below 350.degree. C. According to this process, it is possible to produce a clay mineral of chain structure in a simple, stable manner.

Process for producing clay mineral of chain structure

A composite material comprising a resin other than polyamide resin and a layered silicate dispersed therein, said layered silicate having a layer thickness of 7 to 12 .ANG. and an interlayer distance of 30 .ANG. or above. Owing to the layered silicate uniformly dispersed in the resin matrix, the composite material is superior in mechanical characteristics and heat resistance. It also has good water resistance and chemical resistance.
