Discussion
Assertion (A): Silicon carbide kiln furniture can be made thinner than cordierite furniture of the same load capacity.
Reason (R): It is considerably stronger and conducts heat far better, so thin sections perform well.
Answer: A
Correct answer: Both A and R are true, and R is the correct explanation of A
Both are true and the reason gives both halves. The greater strength allows a thinner section to carry the same load, and the high thermal conductivity keeps the thin section from developing damaging gradients as the kiln heats and cools. The result is furniture of far lower mass - which matters because every kilogram of it is heated and cooled on every cycle at the ware’s expense.
