Gallium sulfide

Schwefel gallium, n. gallium sulfide, -gehalt, m. sulfur content. 

GaUium is widely distributed in nature, mostly found in trace amounts in many minerals including sphalerite, diaspore, bauxite, and germanite. It is found in aU aluminum ores. Gallium sulfide occurs in several zinc and germanium ores in trace amounts. It also is often found in flue dusts from burning coal. Abundance of this element in the earth s crust is about 19 mg/kg. Its average concentration in sea water is 30 ng/L. 

Although gallium sulfide does not precipitate from a solution of the pure salt, it is readily carried down with zinc sulfide. Boisbaudran therefore added ammonium acetate and acetic acid to the hydrochloric acid solution of the above precipitate, and passed in hydrogen sulfide. As long as the line Ga a (417 0) continued to show in the spectrum of the precipitate, he kept on adding zinc to the filtrate until finally all the gallium had been precipitated. 

Gallium has a stronger tendency to react with sulfur ligands than has aluminum. This is evident in the chemistry of gallium sulfides and related species, and in the fact that Ga forms... 

Aluminum and Gallium Sulfides. The crystal structures of the various forms of A12S3 were studied by Flahaut (2) and those of Ga2S3 by Hahn and his coworkers (13, 15). These crystal structures are similar, and closely related to the wurtzite and zinc blende types.
