Chemistry - Metallurgy Question with Solution | TestHub

Question Explanation: State the role and application of the Calcium Silicate ( ${\mathrm{CaSiO}}_3$ ) slag formed in the extraction of iron.

Concept:

Slag in Iron Extraction.

Solution:

${\mathrm{CaSiO}}_3$ slag is formed from CaO (flux) and ${\mathrm{SiO}}_2$ (impurity).

Slag is lighter and floats on the molten iron, thus preventing the reoxidation of the molten iron. Slag is also recovered as a useful by-product and is used in the cement industry and as building material.

Final Answer: prevents the reoxidation of molten iron. and is used in cement industry.
