Refractory bricks are specialized bricks designed to withstand high temperatures without breaking down. They are commonly used in furnaces, kilns, and fireplaces, where extreme heat is generated. Made from materials like clay, alumina, and silica, these bricks can endure thermal shock and resist chemical corrosion. These bricks come in various types, each suited for specific applications. For example, fireclay bricks are often used in industrial settings, while insulating bricks help retain heat and improve energy efficiency. Their durability and heat resistance make refractory bricks essential in industries such as metallurgy and ceramics.
