Introduction Name:Potassium Nitrate CAS NO:7757-79-1 UN No:1486 Formula:KNO3 Formula Weight:101.10 Apperance:Granular Assay:99.9% Application Tech grade Potassium Nitrate plays a role in temperature hardening glass, also used as a glass clarifier. The glass or glass products that need to be tempered are placed in high temperature molten potassium nitrate salt to soak for a certain time, through the replacement reaction of potassium ion in molten potassium nitrate salt and sodium ion in glass, because the diameter of potassium ion is larger than that of sodium ion, so as to form compressive stress on the glass surface, so as to improve the glass strength. 99.9% Tech grade Potassium Nitrate Granular is mainly applied in TV glass,glass refining agent and motor light glass,fireworks and black powder,drugs and catalyzer,ceramic and enamel,compound fertilizer and foliar fertilizer.
