Which one of the following slag components is responsible for the oxidizing power of steelmaking slags?
Show Hint
- SiO\(_2\)
- CaO
- MgO
- FeO
The Correct Option is D
Solution and Explanation
Step 1: Understanding the slag components - SiO\(_2\) (Option A): Silicon dioxide is an acidic component of slag and is primarily involved in the formation of silicate compounds, not in oxidizing power.
- CaO (Option B): Calcium oxide, also known as lime, helps in fluxing and removing impurities but is not the primary oxidizing agent.
- MgO (Option C): Magnesium oxide is also a component of slag, but it primarily acts as a stabilizer and flux, not an oxidizer.
- FeO (Option D): Iron(II) oxide is responsible for the oxidizing power in steelmaking slags. FeO can act as an oxidizing agent, promoting the oxidation of carbon and other impurities in the slag phase.
Step 2: Conclusion The component responsible for the oxidizing power of steelmaking slags is FeO (Option D).
