Which refractory must have controlled atmosphere (temperature and humidity) for its safe storage ?
Correct answer: A. Tar bonded dolomite bricks
- A. Tar bonded dolomite bricks
- B. Fireclay bricks
- C. Mullite bricks
- D. Magnesite bricks
Explanation
Tar-bonded dolomite bricks can deteriorate through moisture-related hydration of free lime and magnesia, so temperature and humidity must be controlled during storage. The other listed refractories are much less sensitive to such storage conditions.
