ABSTRACT:
A dry alkaline earth metal metasilicate or an alkali metal metasilicate is chemically reacted with a concentrated mineral acid in the ratio of 1:3 mols to produce silicoformic hydrogen salts and an alkali hydrogen salt. The silicoformic hydrogen salt is washed with water then filtered to remove the salt and mineral acid, thereby producing silicoformic acid.
