antimonide

-ide.] Chemistry: A compound of antimony and some other element or metal. ăn-ti-mon-if-er-ous, a . Mediæv. Lat. an tim onium, and Cla . Lat. fero = to bear.] Bearing antimony; an tim on i a ted (q.v.) ăn-ti-mō-ni-ous, a. [Eng. antimony: -ous.] Containing as one of its ingredients antimony. Antimonious chloride, or antimony trichloride, SbCl3, called also butter of antimony. By di olving the metal or the sulphide in strong HCl, and distilling the liquid, SbCl3 volatilises and forms a white crystalline ma . Antimonious oxide, or antimony trioxide , Sb2O3. Obtained by decomposing SbCl3 with an alkaline carbonate. It is a colourle powder, crystallising in octohedra; it becomes yellow when heated, melts at red heat, and volatises in a close ve el, but absorbs oxygen from the air, and becomes Sb2O4. Antimonious oxide di olves in cream of tartar, forming tartar emetic, or pota ium antimony tart a rate, 2(C4H4K(SDO)06) + H2O. Antimonious sulphide, SboS3, occurs native as a lead-grey, shining, crystalline, brittle mineral; sp. gr. 46; easily fusible, and a good conductor of electricity. It is used in horse medicine and in Bengal lights. When precipitated by H2S it is an orange-red powder, which is soluble in ammonium sulphide. Kermes mineral is a mixture of Sb2S3 and Sb2O3. Sulph - antimonites are compounds of Sb2S3 with basic sulphides. Antimony pent a sulphide, or antimonic sulphide, Sb2S5, is a yellow-red powder obtained by decomposing sodium sulph antimoniate, NagSbS4, a crystalline substance.
