Refractory materials are substances that can withstand very high temperatures without degrading or breaking down. They are used in a variety of industrial applications such as in furnaces, kilns, and reactors where high temperatures are required. Research in the area of refractory materials focuses on developing new materials with improved heat resistance, durability, and thermal shock resistance. This research often involves studying the properties of different types of refractory materials, as well as exploring new manufacturing processes and technologies to produce more efficient and cost-effective materials.
