High refractoriness of refractory bricks means, that it has a________________?
Correct answer: C. High resistance to fusion
- A. High spalling resistance
- B. Low spalling resistance
- C. High resistance to fusion
- D. Low porosity
Explanation
Refractoriness is the ability of a refractory material to withstand very high temperatures without softening or fusing. Spalling resistance and porosity are separate properties, so resistance to fusion is the defining feature.
