Antimony is increasingly being used in semiconductors as a dopant in n-type silicon wafers for diodes, infrared detectors, and Hall-effect devices. In the 1950s, the emitters and collectors of n-p-n alloy junction transistors were doped with tiny beads of a lead-antimony alloy. Indium antimonide is used as a material for mid-infrared detectors.
Mar 03, 2011· Exposure to antimony occurs in the workplace or from skin contact with soil at hazardous waste sites. Breathing high levels of antimony for a long time can irritate the eyes and lungs, and can cause problems with the lungs, heart, and stomach.

Antimony occurs naturally in the earth. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. Antimony breaks easily, but when mixed into alloys, it is used in lead storage batteries, solder, sheet and pipe metal, bearings, castings, and pewter.
from the production of lead, copper, gold, and antimony . The large production volumes, especially for copper and lead, mean that these residues have the potential to replace a large portion of the primary antimony production . Secondary antimony sources also include end-of-life products such as lead-acid batteries, plastics with anti-
Lead shot is classified in very general names that refer to antimony alloy content. The two types of lead shot are known as either chilled or magnum. Antimony is the alloying metal used to harden lead. Antimony is a brittle flaky, crystalline metal with a density of 6.7 grams/cc. Pure lead…
Lead-antimony litharge – like lead-bismuth alloy – is used as starting material that is refined into its individual elements. The lead recovered in this process is used first and foremost in the battery industry. Antimony, a silvery, shiny, brittle semimetal, is used primarily to produce antimony trioxide, a …
most common battery chemistries used in the U.S. for lead-acid batteries were the high-antimony lead alloy compositions. Antimony was first identified and used as an alloy to lead grids as far back as 1881, because of the good properties it gave to the alloy in terms of strength, handling, and improved production casting.

Lead - Antimony alloys have high corrosion resistance in most enviroments. They form a protective, impermeable film even faster than pure lead and in some cases even faster than chemical lead. It is found that except in the presence of florine compunds, 6% antimonial lead is more resistant to corrosion than is soft lead. 6% Antimony, 92% Lead this is by far the most popular with target shooters.
