Ground granulated blast-furnace slag - Wikipedia

The chemical composition of a slag varies considerably depending on the composition of the raw materials in the iron production process. Silicate and aluminate impurities from the ore and coke are combined in the blast furnace with a flux which lowers the viscosity of the slag. In the case of pig iron production the flux consists mostly of a mixture of limestone and forsterite or in some cases dolomite. In the blast furnace the slag floats on top of the ironand is decanted for separation. Slow cooling of slag melts …

Blast Furnace Slag - an overview | ScienceDirect Topics

As slag is generated at high temperature as a liquid in the blast furnace during iron production and subsequently quenched, its composition is essentially that of an overcharge-balanced calcium aluminosilicate framework – i.e., there is more than sufficient calcium available to charge-balance aluminium, with the remainder contributing to depolymerizing the glass network (Tsuyuki and Koizumi ...
