Gallium(III) Chloride (GaCl₃)

Gallium(III) Chloride (GaCl₃), also known as Gallium trichloride, is an opaque to white crystal/powder with an acidic odor. It acts as a weak inorganic acid and is soluble in virtually all solvents, including alkanes, an unusual chemical property for a metal halide.
Gallium(III) Chloride is highly corrosive and hygroscopic.

Gallium Content (wt %): 39.59%

Purity: 5N (99.999%)
Typical Applications

Gallium(III) chloride is used as a raw material in the production of metallic gallium and the processing of mono-crystal semiconductor compounds. It is also used as a catalyst in many organic synthesis reactions, including the trimerization of alkynes. Other uses of Gallium(III) Chloride are to detect solar neutrinos and as an electrolyte additive in Lithium Thionyl Chloride (Li-SOCl₂) primary batteries.

Packaging Options

Gallium Trichloride is a challenging material to handle and transport responsibly so accommodations to establish UN/DOT-certified packaging that allows safe transportation will be arranged
