Refractory materials are specialized substances designed to withstand high temperatures without melting or deforming. They are commonly used in industries that involve extreme heat, such as metal production, glass manufacturing, and ceramics. These materials can resist thermal shock and chemical corrosion, making them essential for furnaces, kilns, and reactors. Common types of refractory materials include fireclay, silica, and magnesia. Each type has unique properties that make it suitable for specific applications. For example, fireclay is often used in brick form for lining furnaces, while silica is valued for its high melting point and durability in glass production.
