Introduction to Alumina Bricks
Alumina bricks are a type of refractory material that are widely used in various industrial applications due to their excellent thermal and mechanical properties. These bricks are made primarily from alumina (Al₂O₃), which gives them high refractoriness, good chemical stability, and resistance to thermal shock. Alumina bricks can withstand high temperatures, typically up to 1700 - 1800°C, making them suitable for use in furnaces, kilns, and other high - temperature processing equipment. They are also resistant to corrosion from molten metals, slag, and gases, which helps to extend the service life of the industrial facilities where they are installed.
