Antimony trioxide is the most important of the antimony compounds and is primarily used in flame-retardant formulations. used in the past to treat Schistosomiasis today Praziquantel is universally usedĪntimony compounds in the form of oxides, sulfides, sodium antimonate, and antimony trichloride are used in the making of flame-proofing compounds, ceramic enamels, glass, paints, and pottery.main and big-end bearings in internal combustion engines (as alloy).soldering - some "lead-free" solders contain 5% Sb.The most important use of antimony is as a hardener in lead for storage batteries. As an alloy, this metalloid greatly increases lead's hardness and mechanical strength. According to New Scientist ( ) the earth has an estimated thirty years supply left of this element however, with anticipated increases in demand the supply could be exhausted in 15 years.Īntimony is increasingly being used in the semiconductor industry in the production of diodes, infrared detectors, and Hall-effect devices. Antimony is geochemically categorized as a chalcophile, occurring with sulfur and the heavy metals lead, copper, and silver.Įstimates of the abundance of antimony in the Earth's crust range from 0.2 to 0.5 ppm. Antimony and some of its alloys are unusual in that they expand on cooling. It is also attacked by oxidizing acids and halogens.
A metalloid, antimony resembles a metal in its appearance and in many of its physical properties, but does not chemically react as a metal. Antimony is used in flame-proofing, paints, ceramics, enamels, a wide variety of alloys, electronics, and rubber.Īntimony in its elemental form is a silvery white, brittle, fusible, crystalline solid that exhibits poor electrical and heat conductivity properties and vaporizes at low temperatures. Yellow and black antimony are unstable non-metals.
The stable form of antimony is a blue-white metalloid. A metalloid, antimony has four allotropic forms.
