Coke used for the production of calcium carbide should have____________________?
Correct answer: A. All A , B. and C.
- A. All A , B. and C.
- B. Low ignition temperature
- C. High electrical resistivity
- D. Low ash content
Explanation
Calcium carbide is produced in an electric furnace, so the coke should contribute little ash, ignite readily, and have high electrical resistivity for efficient furnace heating. Thus all listed properties are desirable.
