Semi-silica bricks compared to silica bricks have_______________?
Correct answer: C. Both A. and B.
- A. Less fusion point
- B. Better spalling resistance
- C. Both A. and B.
- D. Neither A. not B.
Explanation
Semi-silica bricks contain less silica than silica bricks, giving them a lower fusion point, while their lower quartz content improves resistance to thermal spalling. Both stated properties therefore apply.
