Antimony (Sb) is a silver-white brittle solid or a dark-gray, lustrous powder. It can be harmful to the eyes and skin. Antimony can also cause problems with the lungs, heart, and stomach. Workers may be harmed from exposure to antimony and its compounds. The level of exposure depends upon the dose, duration, and work being done.

Antimony Oxide Listing Background Document for … Antimony sulfide contained in an antimony sulfide bearing ore, such as stibnite, is converted to high purity antimony trichloride by reacting the antimony sulfide bearing ore with a source of chlorine to form high purity antimony trichloride and sulfur or hydrogen sulfide as separable by-products.
Antimony plays an important role in the performance of cycling batteries. As the batteries are cycled, antimony from the grid is deposited into the active material adjacent to the grid wires. The antimony doping permits the battery to be recharged without the development of passive layers between the grid and the active material.
In this work, we have investigated the effect of Antimony counter-doping in channel region of 4H-SiC MOSFETs with moderately doped p-body, relevant for power applications. Using this process, improved sub-threshold slope and high channel mobility have been achieved in conjunction with high threshold voltage. Our results indicate that the improvement in transport is associated with Sb …

This process results in molten lead and dross. Dross refers to the lead oxides, copper, antimony and other elements that float to the top of the lead. Dross is usually skimmed off and sent to a dross furnace to recover the non-lead components which are sold to other metal manufacturers. The Parkes process is used to separate silver or gold from ...

Antimony roaster project Oman - ERG Process Technologies. Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb 2 S 3.This soft grey material crystallizes in an orthorhombic space group. It is the most important source for the metalloid antimony. The name is from the Greek στίβι stibi through the Latin stibium as ...
Antimony. Antimony is a semimetallic chemical element which can exist in two forms: the metallic form is bright, silvery, hard and brittle; the non metallic form is a grey powder. Antimony is a poor conductor of heat and electricity, it is stable in dry air and is not attacked by dilute acids or alkalis.

Antimony, tin, arsenic, and calcium are the most common alloying elements. Antimony generally is used to give greater hardness and strength, as in storage battery grids, sheet, pipe, and castings. Antimony contents of lead-antimony alloys can range from 0.5 to 25%, but they are usually 2 to 5%.
Antimony is present in 80 – 85% of all PET. Antimony is a carcinogen, and toxic to the heart, lungs, liver and skin. Long term inhalation causes chronic bronchitis and emphysema. The industry will say that although antimony is used as a catalyst in the production process, it is "locked" into the finished polymer, and not a concern ...
Assessment and Distribution of Antimony in Soils around (2 g/L), and the World Health Organization (20 g/L) also have drinking water standards for Sb.7 Heavy metal contamination in soils and groundwater is one of the large-scale threats to the environment and human health that has resulted from the industrial and population expansion of the 20th century.8 One of the major sources of heavy ...
The PET manufacturing process uses antimony trioxide as a catalyst. Another main use of antimony trioxide is as a flame retardant synergist in combination with brominated compounds in flame retarding plastics. However, antimony trioxide cannot be used in the case of PET for two main reasons.
