Calcium Fluoride - an overview | ScienceDirect Topics

Klas Weman, in Welding Processes Handbook (Second Edition), 2012. Basic electrodes. Basic electrodes contain calcium fluoride (fluorspar – CaF 2) in the coating.The slag reacts as a base, thus leaving low sulphur and oxygen contents in the weld metal. The strength and toughness of the weld are therefore the strongest welds produced by any type of electrode, and the resistance to hot cracking
