Gallium chloride (GaCl3), also known as gallium trichloride or gallium(III) chloride, is a colorless solid which dissolves easily in most solvents. Gallium trichloride is generally produced in one of two ways:

  • Preparation of heated gallium and chlorine followed by sublimation under vacuum
  • Heating gallium oxide with thionyl chloride


The vast majority of gallium trichloride is used in the production of more commercially valuable gallium products.

  • Gallium chemistry. Gallium trichloride is a trihalide Lewis acid, the most widely used of the gallium trihalides. GaCl3 is extensively used in the production of precursor materials for advanced chemical compounds, including tri-methyl gallium and other organometallic compounds. It’s considered a key component in organogallium chemistry for this reason. 
  • Neutrino detection. Outside of its applications in organogallium chemistry and other chemical production, gallium chloride is used in academics as a material for solar neutrino detection. To do so, researches collected 110 tons of aqueous gallium chloride solution, then measured the decay of germanium-71 which resulted from the interaction of gallium-71 isotopes in the solution with neutrinos.

AHP Materials offers gallium trichloride at 99.999% and 99.9999% purities as part of our standard product catalog. To ask about other preparations of GaCl3, or to inquire about materials not listed on our catalog, contact us today for a custom order.
