Boron Trichloride (BCI3)

Boron trichloride (BCl3) is a toxic, colorless, corrosive gas produced as a liquid under its own vapor pressure. Sioux Falls customers who want a reputable, local producer of boron trichloride should contact A-OX Welding Supply at 605-336-1125.

Boron trichloride has a number of known uses, including as a starting material for the manufacture of elemental boron. It has been historically identified with the preparation and refining of aluminium, magnesium, zinc, and copper alloys to get rid of nitrides, carbides, and oxides from molten metal, although many 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 once used in the manufacture of electrical resistors, to help create a carbon film over a ceramic base. At this time, 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 provided to many chemical research facilities and universities for use as a reagent in the synthesis of organic chemicals.
