Carbon refractories have very high __________________?
Correct answer: D. Both B. and C.
- A. Wetting characteristics
- B. Refractoriness
- C. Thermal conductivity
- D. Both B. and C.
Explanation
Carbon refractories combine high refractoriness with high thermal conductivity, allowing them to tolerate severe temperatures and transfer heat effectively. Their low wettability, rather than high wettability, helps resist penetration by molten materials.
