Not illustrated. 1883 Excerpt: ...when the prismatic form is slowly sublimed in a non-oxidising atmosphere. The mineral ejeitile is prismatic oxide of antimony, and senartnontite is the octahedral form of that oxide. "When heated in air the oxide assumes a yellow colour, afterwards takes lire, moulders, and becomes converted into the antimonious antimoniato (Sb, Os.SbaOs = Sb., ()4), which was formerly regarded as an independent oxide. The sesquioxide is insoluble in water, but acids dissolve it, forming salts, though its basic properties are weak, and its salts rather ill defined. Potash and soda are also capable of dissolving it, whence it is sometimes called antimonious anhydride, corresponding to nitrous anhydride. Two crystallised antimonites of xodium have been obtained, the neutral antimonite lSraSbOa.6Aq., and the teraiitimoniteXaSbO., .Sb.,0.i.Aq.: the former is sparingly soluble, the latter almost insoluble in water. Antimonic oxide (Sba05) is formed when antimony is oxidised with nitric acid; it then forms a white powder, which should be well washed and dried. When heated it becomes pale yellow, and is decomposed at a high temperature, leaving Sb./.Sh.O.. It is dissolved by solution of potash, forming potassium antimoniate. Antimonic acid HSbO: j, corresponding to nitric acid, is obtained by decomposing antimonic chloride with water; SbCl5 + SH.,0 = HSb03 + 5HC1. Antimonic hydrate, dried over sulphuric acid, is Sbo05.3HaO. At 100 ('. it becomes Sb205.2H20. At about 200, it is Sba0, .H2O. These may be represented, respectively, as II3Sb04, H4Sb20-, and HSbOs, corresponding to ortho-, pyro-and nietaphosphoric acids. Potassium antimoniate is made by gradually adding 1 part of powdered antimony to 4 parts of nitre fused in a clay crucible. The mass is powdered and washed with warm wa...
