Description

Lithium Pentaborate is an inorganic boron-lithium compound with the chemical formula LiB5O8. This specialty chemical is valued for its role as a high-purity source of both lithium and boron in advanced material synthesis and glass manufacturing. It is primarily utilized in industries such as specialty glass and ceramics, electronics, and nuclear technology for its unique fluxing and neutron absorption properties.

Application

• Specialty Glass & Ceramics: Acts as a high-performance flux and stabilizer in the production of low-melting-point glasses, enamel frits, and ceramic glazes.
• Electronics & Semiconductors: Serves as a dopant or precursor material in the fabrication of electronic ceramics and specialized optical components.
• Nuclear Shielding: Utilized in radiation shielding applications due to the neutron absorption capabilities of the boron-10 isotope.
• Laboratory Reagent: Employed as an analytical standard or reagent in chemical analysis and research laboratories.
• Flame Retardants: Used as a component in certain flame-retardant formulations for polymers and textiles.
• Metallurgy: Functions as a fluxing agent in metal refining and welding processes.
