Description

Potassium Metaborate is an inorganic salt of boric acid and potassium, widely utilized for its fluxing and buffering properties. This compound is valued for its ability to lower melting points and modify the chemical reactivity of systems in high-temperature industrial processes. Key industries that rely on this material include glass and ceramics manufacturing, metallurgy, and as a component in specialized detergents and cleaning formulations.

Application

• As a fluxing agent in the production of specialty glasses, enamels, and ceramic glazes to reduce melting temperatures.
• In metallurgical processes as a slag modifier and for metal surface treatment.
• As a corrosion inhibitor and buffering agent in aqueous systems and industrial cleaning formulations.
• In the synthesis of other boron-containing compounds and as a laboratory reagent.
• As a component in fire retardant additives and wood treatment chemicals.
• In the formulation of welding and brazing fluxes.
