· K2B4O7

K2B4O7 (potassium tetraborate) is an inorganic ceramic compound belonging to the borate family, commonly known as borax or refined borax derivatives. It is widely used in glass manufacturing, ceramic glazes, and as a flux in metallurgical processes, where its low melting point and glass-forming capability make it valuable for lowering processing temperatures and improving melt fluidity. The material is also employed in detergents, flame retardants, and insulation applications due to its thermal stability and chemical inertness, offering cost-effectiveness and processing advantages over many specialized ceramic alternatives.
