Silicon carbide refractories are used in the _____________?
Correct answer: C. All A., B. and C.
- A. Muffle furnace
- B. Zinc smelting furnace
- C. All A., B. and C.
- D. Ceramic recuperators
Explanation
Silicon carbide refractories resist high temperatures, thermal shock, and chemical attack, so they are used in muffle furnaces, zinc-smelting furnaces, and ceramic recuperators. Therefore, all listed applications are suitable.
