Na2B4O7
ceramic· Na2B4O7
Sodium tetraborate (Na2B4O7), commonly known as borax, is an inorganic ceramic compound and naturally occurring mineral that serves as a raw material and flux in industrial processing. It is widely used in glass manufacturing, ceramic glazes, detergent formulations, and metal joining applications, where it functions as a flux to lower melting temperatures and improve wetting behavior. Borax is valued for its cost-effectiveness, availability, and versatility compared to specialty ceramic binders; engineers select it when economical processing aids and broad chemical compatibility are priorities.
