Boron Trichloride (BCI3)

Boron trichloride (BCl3) is a toxic, colorless, corrosive gas shipped as a liquid under its own vapor pressure. Indianapolis customers who want a high quality, local producer of boron trichloride should reach out to American Welding & Gas, Inc. at .

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

It still experiences 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 previously used in the production of electrical resistors, to help create a carbon film over a ceramic base. Currently, most Ultra High Purity Boron Trichloride (BCl3) is applied 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 distributed to many chemical research facilities and universities for use as a reagent in the synthesis of organic chemicals.
