Which one contains maximum percentage of Al2O3 ?
Correct answer: B. Sillimanite
- A. Firebrick
- B. Sillimanite
- C. Magnesite
- D. Aluminous firebrick
Explanation
Sillimanite contains about Al2O3, more than ordinary firebrick and magnesite; aluminous firebrick commonly has a lower alumina content than sillimanite. Its high alumina content gives sillimanite good refractoriness and load-bearing ability.
