Abstract
Spheroidal aggregates of highly absorbent, low bulk density, readily soluble, high surface area, hydrated, amorphous alkali metal silicate are provided by contacting discrete alkali metal silicate particles with an aqueous solution of hydrogen peroxide, absorbing the peroxide into the alkali metal silicate hydrated structure and heating the silicate to destroy substantially all of the hydrogen peroxide.
