Description

Calcium Borate is an inorganic compound valued for its role as a source of both calcium and boron. This material is essential in industrial processes where controlled release of boron or flame-retardant properties are required. Key industries that utilize this compound include ceramics, glass manufacturing, and the production of specialized flame retardants and wood preservatives.

Application

• As a fluxing agent and stabilizer in the production of specialty glasses and ceramics.
• As a component in flame-retardant formulations for plastics, textiles, and wood treatments.
• As a boron nutrient source in agricultural micronutrient fertilizers.
• In the manufacture of insulation materials such as fiberglass.
• As a corrosion inhibitor in certain lubricants and coatings.
• In metallurgical processes as a slag modifier.
