Product description : Arsenic is a well-known chemical element, element symbol As, atomic sequence 33. The first record of arsenic was made in 1250 by Albertus Magnus. It is a well-known toxic metaloid and has many allotropes. Yellow (molecular structure, nonmetal) and several black and gray (metaloid) are part of the common species. Three endometallic forms of arsenic with different lattice structures occur in nature (arsenite strictly, and the rarer natural arsenite and bismuth and arsenite), but the more commonly found forms are arsenide and arsenate compounds. Altogether hundreds of minerals have been discovered. Arsenic and its host compounds are used in pesticides, herbicides, insecticides and many alloys. At present, metallic arsenic is mainly used as alloy material in copper and lead alloys. In addition, arsenic is also used as a doping material in some semiconductor materials, such as N-type semiconductor materials. With the enhancement of people's awareness of health and environmental protection, the use of arsenic in pesticides, herbicides, wood preservatives, pesticides and other aspects is gradually decreasing.
