The linear thermal expansion of _______________ bricks upto 1000 °C is very low of the order of ≤ 0.5 percent?
Correct answer: A. Fireclay
- A. Fireclay
- B. Silica
- C. Magnesite
- D. Corundum
Explanation
Fireclay bricks have relatively low linear thermal expansion up to about 1000 °C, approximately 0.5%. Silica bricks are especially prone to expansion during quartz transformations, while magnesite generally expands more.
