fluxing in cement industry

fluxing in cement industry

Fluxing Agent - an overview | ScienceDirect Topics

Calcium borates have been shown to be useful fluxing agents in cement manufacture because they lower the viscosity and surface tension of the melt. Their influence on the stabilities and compositions of the calcium silicates can be estimated from the phase diagram for the ternary system CaO-SiO 2-B 2 O 3.This system was first studied by Flint and Wells 68 and the subsolidus phase diagram ...
