In power engineering, what characteristic defines refractory materials?

Refractory materials are specifically defined by their ability to withstand high temperatures without melting or deforming. This characteristic is crucial in the field of power engineering and various industrial applications, as these materials are often used in furnaces, kilns, reactors, and other high-temperature environments. Their thermal stability allows them to maintain structural integrity and performance under extreme conditions, making them essential for processes involving molten metals, hot gases, or other elevated-temperature operations.

Understanding the thermal properties of refractory materials is vital for engineers who design and operate equipment that requires reliable performance in heat-intensive settings. Their selection is based on how well they can resist thermal shock and chemical erosion while maintaining their shape and functionality.
