Silver antimonide

When the stibine-hydrogen mixture is passed into a solution of silver nitrate (Hofmann s test) a black precipitate of silver antimonide Ag3Sb is obtained this is decomposed by the excess of silver nitrate into silver and antimony(III) oxide ... 

Stibine is readily oxidized and may be ignited in the presence of air or oxygen to form water and antimony trioxide at lower temperatures metallic antimony and water are slowly formed. Sulfur and selenium react with stibine at 100°C in the presence of light to form antimony trisulfide [1345-04-6], Sb2S3, and antimony selenide [1315-05-5], Sb2Se3, respectively. At elevated temperatures stibine reacts with most metals to give antimonides. Heavy metal salts react with stibine to produce dark, metallic-appearing precipitates. In the case of silver nitrate, silver antimonide is first formed, and this reacts in turn with additional silver nitrate to produce metallic silver and antimony trioxide ...

The phosphides, arsenides, and antimonides of the other metals are usually dark-coloured substances, with more or less metallic lustre, and therefore conductors of electricity. Some of them occur native for example, smaltine, CoAs2, a common ore of cobalt, forming silver-white crystals copper-nickel, NiAs, red lustrous crystals, and one of the chief nickel ores speiss, a deposit formed in the pots in which smaltine and copper-nickel are fused with potassium carbonate and silica, in the preparation of smalt, a blue glass containing cobalt its formula appears to be Ni8As2. Mispickel, or arsenical pyrites, is a white lustrous substance, of the formula FeSAs. 

Sulfides, Antimonides, Selenides, and Tellurides are minerals in which sulfur, antimony, selenium, or tellurium combine with one or more metals, or with one metal and one semi-metal. Some sulfide minerals are valuable sources of such elements as copper, silver, zinc, and mercury. 

Indium has many industrial uses for electronics and electrical applications [9] indium metal in germanium transistors indium alloys for soldering and glass sealing of electronic devices indium antimonide, arsenide, and phosphide in infrared detectors and semiconductor applications indium-silver alloys for brazing and electroplated indium metal for electrical connectors. For underground telephone cables, indium has been used to plate copper-to-aluminum connectors. About 2-5 tons of indium alloyed with silver and cadmium has been used annually in nuclear reactor control rods.
