The calcination temperature of white cement clinker is higher than that of ordinary portland cement clinker, reaching 1500 ~ 1600 ℃. In order to reduce the calcination temperature, white cement plants usually add CaF 2 as a mineralizer to the raw materials. Some plants also use fluorine or sulfur industrial waste residue as mineralizers.
