Fire bricks, also known as refractory bricks, are specially designed to withstand high temperatures without breaking down. They are commonly used in applications like kilns, fireplaces, and furnaces where intense heat is generated. Made from materials like clay and other minerals, fire bricks can endure extreme conditions while providing insulation. These bricks are typically denser and thicker than regular bricks, which helps them resist thermal shock and maintain structural integrity. Fire bricks come in various shapes and sizes, allowing them to fit different designs and purposes. Their durability makes them essential for any high-heat construction project.
