Arsenic is added in small quantities to alpha-brass to make it dezincification-resistant. This grade of brass is used in plumbing fittings and other wet environments. [110] Arsenic is also used for taxonomic sample preservation. It was also used in embalming fluids historically. [111] Arsenic was used in the taxidermy process up until the 1980s ...
Boron arsenide (or Arsenic boride) is a chemical compound involving boron and arsenic, usually with a chemical formula BAs. Other boron arsenide compounds are known, such as the subarsenide B 12 As 2. Chemical synthesis of cubic BAs is very challenging and its single crystal forms usually have defects.
The arsenic content gives a garlic odor when heated or crushed. Skutterudite was discovered in Skuterud Mines, Modum, Buskerud, Norway, in 1845. [4] Smaltite is an alternative name for the mineral.

In Reentry, his latest book about SpaceX's development, space journalist Eric Berger says the timelines posited by space companies are often wishful thinking, describing what might happen if ...
Arsenic trioxide powder.. Compounds of arsenic resemble in some respects those of phosphorus which occupies the same group (column) of the periodic table.The most common oxidation states for arsenic are: −3 in the arsenides, which are alloy-like intermetallic compounds, +3 in the arsenites, and +5 in the arsenates and most organoarsenic compounds.
Arsenopyrite (IMA symbol: Apy [4]) is an iron arsenic sulfide (FeAsS). It is a hard (Mohs 5.5–6) [5] metallic, opaque, steel grey to silver white mineral with a relatively high specific gravity of 6.1. [1] When dissolved in nitric acid, it releases elemental sulfur. When arsenopyrite is heated, it produces sulfur and arsenic vapor.
