Beryllia (which is used in making crucibles for melting uranium & thorium) is superior to alumina in all respects for high temperature (> 1900°C ) use, except ?
Correct answer: A. Cost
- A. Cost
- B. Electrical conductivity
- C. Thermal conductivity
- D. Fusion point
Explanation
Beryllia has better high-temperature performance than alumina, including higher thermal conductivity and a higher fusion point, but it is much more expensive. Cost is therefore the exception.
