Antimony Powder
The number of electrons in each of antimony's shells is 2, 8, 18, 18, 5 and its electron configuration is [Kr] 4d 10 5s 2 5p 3. The antimony atom has a radius of 140 pm and a Van der Waals radius of 206 pm. Antimony was discovered around 3000 BC and first isolated by Vannoccio Biringuccio in 1540 AD.

Plan for Sole Antimony Mine in U.S. Gets Key Authorization
Further, Niehuser pointed out that the U.S. has an inadequate supply of antimony in its National Defense Stockpile, 1,100 tons at the end of last year, according to the USGS. In comparison, the U.S. consumed 22,000 tons of antimony in 2023. The analyst approximated that Stibnite could backstop about half of U.S. antimony consumption for six years.

The effects of Sb/In (with a loading x of 1, 2, 3 wt.%) in the Sn5Bi solder alloy on the melting properties, microstructures, and the shear behavior of solder/Cu joints were investigated combined with the corresponding phase diagram. It is found that the addition of Sb reduces the melting range and supercooling with the increase of Sb content caused by SbSn …
Antimony, Chemical Element
Antimony is a metalloid. A metalloid is an element that has characteristics of both metals and non-metals. The metalloids can be found on either side of the staircase line on the right side of the periodic table (with the exception of aluminum, which is not considered a metalloid). Antimony is primarily used in alloys, ceramics and glass, plastics, and flame retardant materials.
