Description

Sassolite is the naturally occurring mineral form of boric acid, a fundamental inorganic compound with the chemical formula H₃BO₃. This high-purity grade is essential for industrial processes requiring consistent quality and reliable performance. It serves as a critical raw material and intermediate for manufacturers in the glass, ceramics, agriculture, and flame retardant sectors, where precise chemical properties are paramount for product integrity.

Application

• Glass & Ceramics Manufacturing: A key fluxing agent to lower melting temperatures and improve the thermal and chemical resistance of borosilicate glass, fiberglass, and ceramic glazes.
• Flame Retardants: Used as a component in cellulose insulation, textiles, and wood treatments due to its ability to release water and form a protective glassy layer when heated.
• Agriculture & Horticulture: Acts as a micronutrient fertilizer to correct boron deficiencies in crops and is used in non-selective herbicide formulations.
• Metalworking & Metallurgy: Employed as a flux in welding and brazing to dissolve metal oxides and as a neutron absorber in nuclear applications.
• Chemical Synthesis: Serves as a precursor for the production of various boron compounds, including boron oxides, borates, and boron esters.
• Preservatives & Biocides: Utilized in mild antiseptic solutions, wood preservatives, and as a fungistatic agent.
