Calcium Metal - an overview | ScienceDirect Topics

Smelting to give the metals involves metallothermic reduction of fluorides or oxides, or electrochemical methods. Metal oxides are converted to fluorides by HF/Ar and purified by melting in an HF/Ar atmosphere. The fluorides are then reduced by the more electropositive calcium metal. 2 LnF 3 + 3 Ca → 3 CaF 2 + 2 Ln.

Cesium-137 | Cs - PubChem

Cesium Cs 137 is a radioactive isotope of cesium with an atomic mass of 139 and potential appliion in radiotherapy. Cesium Cs 137 is prevalent due to its spontaneous production, which occurs as a result of nuclear fission of other radioactive materials, such as uranium and plutonium.This radionuclide has a relatively long half-life, 30 years, and decays by emitting beta particles.

How is calcium stored in a lab? - ProProfs Discuss

08/02/2019· I cannot find information specific to calcium. The general principles of storage of chemicals in a lab is to keep like with like. You must avoid contaminating one substance with another.
