Boron Trichloride (BCI3)

Boron trichloride (BCl3) is a colorless, toxic, corrosive gas shipped as a liquid under its own vapor pressure. Minneapolis customers who want a well-established, local producer of boron trichloride should reach out to Toll Company at 612-581-9889.

Boron trichloride has an assortment of traditional uses, including as a starting material for the manufacture of elemental boron. It has been traditionally associated with the preparation and refining of aluminium, magnesium, zinc, and copper alloys to eliminate nitrides, carbides, and oxides from molten metal, although many of these processes have moved away from North America.

It still finds some use when mixed with other compounds as a soldering flux for alloys of aluminium, iron, zinc, tungsten, and monel. Most BCl3 in North America was used before in the production of electrical resistors, to help create a carbon film over a ceramic base. Right now, most Ultra High Purity Boron Trichloride (BCl3) is utilized in plasma etching in semiconductor manufacturing. This gas etches metal oxides by formation of boron chlorates.

Cylinder quantities of PurityPlus® High Purity Boron Trichloride are also supplied to many chemical research facilities and universities for use as a reagent in the synthesis of organic chemicals.
