Because of its very high refractoriness of the order of __________ °C, silicon carbide refractories are used in zinc smelting furnace, muffle furnace and for supporting the wares in tunnel kilns ?
Correct answer: D. 2700
- A. 1800
- B. 2200
- C. 2400
- D. 2700
Explanation
Silicon carbide refractories have an extremely high refractoriness, commonly quoted at about 2700°C. Their high thermal conductivity and resistance to thermal shock make them useful in furnaces and kiln supports.
