Lead Antimonide |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Lead Antimonide is used in a number of industrial applications including infrared detection and imaging. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement. Lead is a Block P, Group 14, Period 6 element. The electronic configuration is [Xe] 4f14 5d10 6s2 6p2. In its elemental form lead's CAS number is 7439-92-1. The lead atom has a radius of 175.pm and it's Van der Waals radius is 202.pm. Lead is a bluish-white metal of bright luster, naturally occurring as a mixture of four stable isotopes: 204Pb (1.48%), 206Pb (23.6%), 207Pb (22.6%), and 208Pb (52.3%). It is highly resistant to corrosion and can be used to contain corrosive liquids such as sulfuric acid. Great quantities of Lead, both as the dioxide and the metal, are used in batteries, cable covering, plumbing, and ammunition. Alloys include solder, type metal, and various antifriction metals and compounds. Lead is extremely effective at absorbing sound and vibration. It is also used as radiation shielding for X-ray equipment and nuclear reactors. Oxides of Lead are used in producing fine "crystal glass" and "flint glass" of a high index of refraction for achromatic lenses. Lead ceramics and crystalline material have a wide range of industrial and optical applications, including infrared detection and imaging. Lead-based semiconductors, such as lead telluride, lead selenide and lead antimonide are finding application in photovoltaic (solar energy) cells and infra red detectors. 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. American Elements semi conducting materials are crystal structures produced from ultra high purity starting materials synthesized by our high purity production facility which includes several large electric muffle furnaces, a tube furnace for hydrogen reduction, 50 gallon glass-lined Pfaudler reactors supported by our analytical laboratory containing X-ray diffraction, SEM, AA, BET surface area, and ICP Spectrometry for trace metals analysis.
