  2. Arsenic - Wikipedia

    en.wikipedia.org/wiki/Arsenic

    Phosphorus Deoxidized Arsenical Copper" with an arsenic content of 0.3% has an increased corrosion stability in certain environments. [103] Gallium arsenide is an important semiconductor material, used in integrated circuits. Circuits made from GaAs are much faster (but also much more expensive) than those made from silicon.

  3. Arsenical copper - Wikipedia

    en.wikipedia.org/wiki/Arsenical_copper

    Arsenical copper contains up to 0.5% arsenic which, at elevated temperatures, imparts higher tensile strength and a reduced tendency to scaling. It is typically specified in boiler work, especially locomotive fireboxes. [1] [2] [3] It also helps prevent embrittlement of oxygen-free copper by bismuth, antimony and lead by the

  4. Arsenical bronze - Wikipedia

    en.wikipedia.org/wiki/Arsenical_bronze

    Arsenical bronze is an alloy in which arsenic, as opposed to or in addition to tin or other constituent metals, is combined with copper to make bronze. The use of arsenic with copper, either as the secondary constituent or with another component such as tin, results in a stronger final product and better casting behavior. [1]

  5. Arsenic compounds - Wikipedia

    en.wikipedia.org/wiki/Arsenic_compounds

    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.

  6. Toxic heavy metal - Wikipedia

    en.wikipedia.org/wiki/Toxic_heavy_metal

    The toxic effects of arsenic, mercury and lead were known to the ancients but methodical studies of the overall toxicity of heavy metals appear to date from only 1868. In that year, Wanklyn and Chapman speculated on the adverse effects of the heavy metals "arsenic, lead, copper, zinc, iron and manganese" in drinking water. They noted an ...

  7. Arsine - Wikipedia

    en.wikipedia.org/wiki/Arsine

    In its standard state arsine is a colorless, denser-than-air gas that is slightly soluble in water (2% at 20 °C) [1] and in many organic solvents as well. [citation needed] Arsine itself is odorless, [5] but it oxidizes in air and this creates a slight garlic or fish-like scent when the compound is present above 0.5 ppm. [6]

  9. Metalloid - Wikipedia

    en.wikipedia.org/wiki/Metalloid

    The heavier metalloids continue the theme. Arsenic can form alloys with metals, including platinum and copper; [112] it is also added to copper and its alloys to improve corrosion resistance [113] and appears to confer the same benefit when added to magnesium. [114] Antimony is well known as an alloy-former, including with the coinage metals.
