Boron Trichloride (BCI3)

Boron trichloride (BCl3) is a corrosive gas that is colorless and toxic and is delivered as a liquid under its own vapor pressure. Western Michigan customers who want a high quality, local producer of boron trichloride should reach out to GTW at 616-754-6120.

Boron trichloride has an assortment of classic utilizations, including as a starting material for the manufacture of elemental boron. It has been historically connected with the preparation and refining of aluminium, magnesium, zinc, and copper alloys to get rid of nitrides, carbides, and oxides from molten metal, although most 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 once used in the manufacture of electrical resistors, to help create a carbon film over a ceramic base. Currently, most Ultra High Purity Boron Trichloride (BCl3) is used 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 development of organic chemicals.
