Which property describes the ability to withstand high temperatures without melting or losing shape over time?

• A. Fire Resistance
• B. Refractoriness
• C. Chemical Resistance
• D. Durability

Answer: (B)

The ability to withstand high temperatures without melting or losing shape over time is refractoriness. This property describes how well a material remains solid and retains its dimensional integrity when exposed to heat, resisting softening or melting during prolonged high-temperature service. It’s crucial for components like furnace linings and kilns that must stay intact under extreme heat. Fire resistance is broader, focusing on protection from flames or heat transfer, not necessarily maintaining shape at high temperature. Chemical resistance concerns reactions with aggressive substances, and durability covers general resistance to wear and degradation, not specifically heat stability.
