Sodium borate (NaBO2) is an inorganic ceramic compound belonging to the borate family, commonly produced as a glassy or crystalline solid with moderate stiffness and density. It appears industrially as a precursor and intermediate in boron-based manufacturing processes, where it serves roles in glass production, metal flux applications, and specialized ceramic formulations. Engineers select sodium borate compounds for applications requiring boron's unique thermal and chemical properties—such as flux behavior in welding and brazing, incorporation into specialty glass compositions for thermal or chemical resistance, and use in ceramic coatings and refractory systems where borate chemistry provides advantages in melting point control or melt viscosity.
