Mullite is chemically represented by_________________?
Correct answer: C. 3Al2O3. 2SiO2
- A. Al2O3. 2SiO2
- B. Al2O3. SiO2
- C. 3Al2O3. 2SiO2
- D. 2Al2O3. 3SiO2
Explanation
Mullite is the aluminosilicate compound 3Al2O3·2SiO2. It is valued in refractories for its high-temperature stability and low expansion.
