Q291
The chemical composition of basic slag is
A.
Ca3(PO4)2
B.
(CaO)3P2O5, SiO2
AnswerC.
(CaO)2P2O5, SiO2
D.
(CaO)3P2O4, SiO4
Answer: Option B
Solution
Answer: Option B
Solution:
The chemical composition of basic slag is (CaO)3P2O5, SiO2.Slag is a by-product of smelting (pyrometallurgical) ores and used metals.
Basic slag systems are made up primarily of limestone, particularly calcium carbonate (CaCO3), which helps provide good impact properties at low temperatures.
Basic slag is low in silica and high in base-forming oxides that are used in the basic process of steelmaking and that are subsequently useful as a fertilizer.
