Boron Trichloride (BCl3)

High-purity boron trichloride (BCl₃) gas for semiconductor doping, boron compound production, organic synthesis catalysis, and steel boriding.

Boron trichloride is a colorless, toxic, and corrosive gas with a pungent, hay-like odor under standard conditions. As an important inorganic compound, it is non-combustible in air but decomposes rapidly in water or alcohol, generating boric acid and hydrochloric acid with significant heat release, and hydrolyzes in moist air to produce fumes. Boron trichloride serves primarily as a doping source for semiconductor silicon, a key raw material for producing various boron compounds (including boron nitride and boranes), an organic synthesis catalyst, a fluxing agent in silicate decomposition, and for boriding steel surfaces, typically transported as a liquefied compressed gas.
