2. It has been found that fluoride is beneficial for reducing clinkering temperature by fluxing action (from 14500C to 13500C). Due to the presence of large quantities of lime and limestone within the kiln, virtually all gaseous fluoride is scrubbed from the kiln exhaust and fixed in the clinker as fluorspar (CaF 2).
