What is the melting point of magnesia bricks?

　　magnesia bricks, also known as magnesite bricks or magnesite-alumina bricks, have a high melting point. The melting point of magnesia bricks typically ranges from approximately 2800°C to 3100°C (5072°F to 5612°F).

　　The exact melting point can vary depending on the specific composition of the magnesia brick, including the content of magnesia (MgO) and any additional additives or impurities present. The purity and quality of the raw materials used in the manufacturing process can also influence the melting point.

　　Due to their high melting point, magnesia bricks are commonly used in applications that involve high temperatures, such as in steelmaking furnaces, cement kilns, glass melting tanks, and other industrial high-temperature environments. Their ability to withstand and retain their structural integrity at extreme temperatures is a key factor in their suitability for these applications.
