The main function of a muffle in the muffle furnace is to__________________?
Correct answer: C. Both A. & B.
- A. Protect the charge from the effects of the products of combustion
- B. Smooth out temperature inequalities on the combustion side of the muffle wall
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
A muffle separates the charge from direct contact with combustion gases and also helps distribute heat more uniformly through its wall. Thus, it performs both protection and temperature-equalising functions.
