Ammonium silicofluoride, CAS 1341-49-7, functions preservative in ferment and textile industry and wood protection. It is also used as disinfectant in brewing and medical industry. Besides, Ammonium silicofluoride, CAS 1341-49-7, is applied as the etchant for glass, sensitizer for aluminum and analytical reagent in electroplate and electronic industry. Ammonium silicofluoride, CAS 1341-49-7, also plays a part in acidified processing for dinas in oil field and surface treatment for silicon steel plate. It serves as the solvent for metal beryllium as well. Ammonium silicofluoride, CAS, 1341-49-7, is deliquescent and would decompose toxic fluoride, nitric oxide and ammonia gas. Thus, it should be kept in cold, dry, well-ventilated warehouse. Keep away from alkali. Operators should wear protective clothing when handling Ammonium silicofluoride.
