Lead fluoroborate

Lead fluoroborate (CAS 13814-96-5, EC 237-486-0), also known as lead fluoborate, lead boron fluoride, and leadborofluoride, is an inorganic lead salt supplied as either a colorless liquid solution or crystalline powder. It carries no assigned E-code and is classified under HS code 28269090.

In electronics manufacturing, lead fluoroborate serves as the active electrolyte in lead electroplating baths, where fluoroborate ions stabilize lead deposition at controlled rates to produce uniform, adherent coatings on circuit components. In mining and metals processing, it functions as a surface conditioning agent, modifying metal oxide layers to inhibit further corrosion through fluoride-mediated passivation.

Lead fluoroborate is available in technical and electroplating grades, typically supplied as an aqueous solution at defined concentrations or as a dry crystalline solid. As a lead compound, it falls under REACH regulation and requires full SDS compliance; buyers should confirm current authorization status and applicable RoHS restrictions before procurement.
