[0002] Refractory materials refer to materials that can withstand high temperatures without being easily damaged. Specifically, refractory materials can maintain relative stability of their physical and chemical properties under high temperature conditions (generally, the refractoriness is not less than 1580°C), such as maintaining a certain strength and volume stability, and can resist erosion and scouring by high-temperature melts (such as molten steel, slag, etc.) and high-temperature gases (such as coal gas, flue gas, etc.).
