ABSTRACT:
Alumina trihydrate particles coated with alkali metal silicate, alkaline earth metal silicate or alumino silicate are useful as fillers in paper and plastics and provide good opacity and brightness properties as well as fire retardancy. The alumina trihydrate products are prepared by reaction of alumina trihydrate with an alkali metal silicate, an alkaline earth metal silicate, or alumino silicate, or the reaction of alkali metal silicate or alkaline earth metal silicate with aluminum sulfate to produce an alumino silicate precipitate coating in situ.
