Tetraiodomethane is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. 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 electronic configuration is [Ar] 4s2. In its elementa 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 member of the alkaline earth elements. 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 purityproperties, research, applications and other useful facts are discussed here. Calcium was first discovered by Sir Humphrey Davy in 1808.
