Boron Trichloride (BCI3)

Boron trichloride (BCl3) is a toxic, colorless, corrosive gas produced as a liquid under its own vapor pressure. El Paso customers who want a well-established, local producer of boron trichloride should reach out to SYOXSA, Inc. at 915-771-7674.

Boron trichloride has an assortment of classic uses, including as a starting material for the creation of elemental boron. It has been traditionally associated 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 has 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 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 distributed to many chemical research facilities and universities for use as a reagent in the development of organic chemicals.
