Zirconia refractory_________________?
Correct answer: B. Is produced from baddeleyite
- A. Does not react with basic slags
- B. Is produced from baddeleyite
- C. Cannot be used as an insulator
- D. Has poor electrical conductivity at high temperature
Explanation
Baddeleyite is the natural mineral form of zirconia, or ZrO₂, and is used as its raw material. Zirconia can serve as an insulating refractory and its electrical conductivity increases at high temperature, so the other descriptions are unsuitable.
