Calcium Arsenate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered.American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Calcium is a Block S, Group 2, Period 4 element. The number of electrons in each of Calcium's shells is 2, 8, 8, 2 and its electronic configuration is [Ar] 4s2. In its elemental form calcium's CAS number is 7440-70-2. The calcium atom has a radius of 197.4.pm and it's Van der Waals radius is 200.pm. Calcium is a reactive, soft metal. Calcium is a member of the alkaline earth elements. Calcium is an essential metal for living organisms and is non-toxic. Its primary commercial application is in its metallic form as a reducing agent in the production of other metals. In iron and steel production it is added to the melt to remove oxygen, sulfur and carbon. The various calcium compounds have wide application in food, pharmaceutical and cosmetics. It is used in small doses in alloys of copper and beryllium. It is used in dietary supplements and food production because it has been shown to improve bone and dental health. Calcium information, including Technical Data, Safety Data and its High Purity properties, research, applications and other useful facts are discussed here. Calcium was first discovered by Sir Humphrey Davy in 1808. The name calcium originates from the Latin word 'calics' meaning lime. See Calcium research below.
Arsenic is a Block P, Group 15, Period 4 element. The number of electrons in each of Arsenic's shells is 2, 8, 18, 5 and its electronic configuration is [Ar] 3d10 4s2 4p3. In its elemental form arsenic's CAS number is 1327-53-3. The arsenic atom has a radius of 124.5.pm and it's Van der Waals radius is 185.pm. Arsenic in the organic form is not harmful but in the inorganic form it is extremely toxic even in very small amounts. Arsenic has numerous applications as a semiconductor and other electronic applications as Indium arsenide, silicon arsenide and tin arsenidea. Arsenic is finding increasing uses as a doping agent in solid-state devices such as transistors. Gallium arsenide is used as a laser material to convert electricity directly into coherent light. Arsenic is used in bronzing and for hardening and improving the sphericity of shot. Due to its toxicity, arsenic compounds are used in insecticides and wood preservation.Arsenic is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Arsenic information, including Technical Data, Safety Data and its High Purity properties, research, applications and other useful facts are discussed here. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included. See Arsenic research below.
