· JVASP-10231· KNa2BO3

KNa2BO3 is a mixed-alkali borate ceramic compound combining potassium and sodium borates, belonging to the family of inorganic oxide glasses and ceramics. This material is primarily investigated in research contexts for applications requiring thermal stability and chemical resistance, particularly in glass-ceramic systems, thermal insulation composites, and specialized refractories. Borate ceramics like this are valued for their low melting temperatures and potential use as fluxing agents or reinforcement phases in composite systems, though KNa2BO3 itself remains largely in developmental stages compared to established single-alkali borate formulations.
