Abstract

The invention relates to a novel silica production method comprising the reaction of a silicate with at least one acid in which the acid used in at least one of the steps is a concentrated acid preferably selected from the group containing sulphuric acid having a concentration of at least 80 wt. % in particular at least 90 wt. % acetic acid or formic acid having a concentration of at least 90 wt. % nitric acid having a concentration of at least 60 wt.% phosphoric acid having a concentration of at least 75 wt. % hydrochloric acid having a concentration of at least 30 wt. %.
