American Elements: Antimony Sulfide Supplier & Tech Info

Antimony Sulfide is a moderately water and acid soluble Antimony source for uses compatible with sulfates. Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal. Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble. Organometallic forms are soluble in organic solutions and sometimes in both aqueous and organic solutions. Metallic ions can also be dispersed utilizing suspended or coated nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots) and deposited utilizing sputtering targets and evaporation materials for uses such as solar energy materials and fuel cells. Antimony Sulfide is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Antimony is a Block P, Group 15, Period 5 element. The electronic configuration is [Kr] 4d¹⁰ 5s² 5p³. In its elemental form antimony's CAS number is 7440-36-0. The antimony atom has a radius of 145.pm and it's Van der Waals radius is 200.pm. Antimony is finding use in semiconductor technology for making infrared detectors, diodes and Hall-effect devices in crystalline structures, such as antimony telluride and gallium antimonide. Antimony is however a poor conductor of heat and electricity. It greatly increases the hardness and mechanical strength of lead. This has found applications in batteries, antifriction alloys, small arms and tracer bullets and cable sheathing. Antimony compounds are used in manufacturing flame-proofing compounds, paints, ceramic enamels, glass, and pottery glazes. Antimony is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder.
