Description

Potassium Borate CAS NO 1332-77-0 is an inorganic salt composed of potassium and borate ions, valued for its role as a source of both potassium and boron. This compound is essential in applications requiring controlled release of boron, a vital micronutrient, and for its flame-retardant and fluxing properties. It is a critical material for manufacturers in the agriculture, ceramics, glass, and chemical synthesis industries seeking reliable, high-purity boron compounds.

Application

• Flame Retardants & Smoke Suppressants: Used as an additive in polymers, textiles, and wood treatments to enhance fire resistance.
• Agricultural Micronutrient Fertilizers: Serves as a source of soluble boron for correcting boron deficiencies in crops.
• Glass & Ceramics Manufacturing: Acts as a flux to lower melting temperatures and improve the thermal and chemical durability of glass and enamel frits.
• Metalworking & Welding Fluxes: Employed in fluxes for brazing and soldering to remove oxides and improve joint quality.
• Lubricant Additives: Functions as an anti-wear and extreme pressure additive in specialty greases and oils.
• Chemical Synthesis: Used as a reagent or catalyst in organic synthesis and for producing other boron-containing compounds.
• Preservatives & Corrosion Inhibitors: Applied in cooling water systems and antifreeze solutions to inhibit corrosion.
