Basicity

(in metallurgy), the ratio (in percent by weight) of basic and acidic oxides in iron ore materials (iron ore, sinter, and pellets), and also in blast-furnace and steel-smelting slag. Basicity defines the chemical composition and metallurgical properties of such materials. In the simplest case, basicity is defined as the ratio of CaO to SiO₂ or of the total of CaO and MgO to that of SiO₂ and Al₂O₃. The processing of iron ore materials requires the calculation of natural basicity and the basicity produced by the addition of flux. Basicity may vary from several tenths of a unit to 2–3.
