Cobalt(II) carbonate Like most transition metal carbonates, cobalt carbonate is insoluble in water, but is readily attacked by mineral acids: Cobalt carbonate is a precursor to cobalt carbonyl and various cobalt salts. It is a component of dietary supplements since cobalt is an essential element. It is a precursor to blue pottery glazes, famously in the case of Delftware. The moderately rare spherocobaltite is the natural form of cobalt carbonate, with good specimens coming especially from the Republic of Congo. "Cobaltocalcite" is a name used for a cobaltiferous calcite variety that is quite similar in habit to spherocobaltite. The compound is harmful
Isotopes of cobalt an excited state of the Fe nucleus, which in turn decays to the ground state with emission of a gamma ray. Measurement of the gamma ray spectrum provides information about the chemical state of the iron atom in the sample. Isotopes of cobalt Naturally occurring cobalt (Co) is composed of 1 stable isotope, Co. 28 radioisotopes have been characterized with the most stable being Co with a half-life of 5.2714 years, Co with a half-life of 271.8 days, Co with a half-life of 77.27 days, and Co with a half-life of 70.86 days. All of the remaining radioactive isotopes have
