실험 절차

About 1 part by weight of dry granular potassium metasilicate, containing less than 6 mols of water per mol of potassium metasilicate, and 12 mols of potassium hydrogen sulfate are mixed. The mixture is agitated at ambient pressure and chemical reaction causes oxygen to evolve in 1 to 3 minutes; considerable heat is produced, 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 dired at 25° to 75° C.
