Triethyl borate

Through continuous technological upgrades, we are now able to reliably supply high-purity triethyl borate to meet the growing demand in the high-end electronic chemicals sector. As a multifunctional boron source and intermediate, the main application areas of triethyl borate include: Semiconductor industry: Used as a boron dopant source in chemical vapor deposition (CVD) processes to produce dielectric thin films such as borosilicate glass (BSG) and borophosphosilicate glass (BPSG). Lithium-ion batteries: As an electrolyte additive, it optimizes the cathode/electrolyte interface, suppresses electrolyte oxidation and decomposition, and improves cycle life and rate performance at high voltages. Organic synthesis: Serves as an important raw material for synthesizing organoboron compounds and as an ethoxylation reagent. Flame retardants: Can be used as a raw material for synthesizing flame-retardant polyols or directly as a flame-retardant additive in polymers such as polyurethane. Specialty coatings and additives: Used as a fluxing agent for soldering, a plasticizer, and a component in high-temperature resistant coatings. Jinhong Gas focuses on the purification of triethyl borate and employs atmospheric distillation to produce high-purity, electronic-grade triethyl borate. Currently, Jinhong Gas has an annual production capacity of 5 tons of high-purity triethyl borate.
