Firing of refractory brick is done to __________________?
Correct answer: E. All A., B. and C.
- A. Dehydrate the dried refractory
- B. Develop stable mineral forms in them
- C. Form ceramic bonds necessary for development of high crushing strength in the finished
- D. product
- E. All A., B. and C.
Explanation
Firing removes chemically bound water, develops stable mineral phases and produces the ceramic bonds responsible for the brick's high crushing strength. Thus all three stated purposes are included.
