Refractory materials are substances that can withstand high temperatures without melting or breaking down. They are commonly used in industries that involve extreme heat, such as metal production, glass manufacturing, and ceramics. These materials help to insulate and protect equipment, ensuring efficient operation in high-temperature environments. Common types of refractory materials include bricks, castables, and ceramics. They are often made from natural minerals like alumina and silica, which provide strength and durability. The ability to resist thermal shock and chemical corrosion makes refractory materials essential for maintaining safety and performance in various industrial processes.
