実験手順

About equal parts by weight of a dry potassium metasilicate, containing less than 6 mols of water per mol of potassium metasilicate, and potassium hydrogen sulfate are mixed. The mixture is agitated at ambient pressure, and the chemical reaction causes oxygen to evolve in 1 to 3 minutes; considerable heat is produced, and the chemical reaction is complete in 1 to 2 hours, thereby producing white granules of a silicic acid compound and potassium sulfate. The mixture is washed with water and filtered to remove the salt. The silicic acid compound is air dried at 25° to 75° C.
