Refractories should have all the following properties EXCEPT
A)Long life
B)Heat insulation
C)High electrical conductivity
D)Minimum contraction and expansion due to temperature variations

Question

Quizplus · Accepted Answer

Refractories are materials that are resistant to high temperatures, used in the lining of furnaces, kilns, incinerators, and reactors. They should have a long life, provide good heat insulation, and have minimum contraction and expansion due to temperature variations to maintain structural integrity under thermal stress. High electrical conductivity is not a required property for refractories; in fact, most refractories are designed to be poor conductors of electricity to better contain heat within a furnace or kiln.
