Introduction：
Magnesia refractory is a type of refractory material made from magnesite (MgO) or dolomite, which is a naturally occurring mineral composed of magnesium carbonate and calcium carbonate. Magnesia refractories have the following characteristics:
1. High melting point: Magnesia refractories have a very high melting point, typically around 2800°C, which makes them ideal for use in high-temperature applications.
2. Good thermal shock resistance: Magnesia refractories can withstand sudden temperature changes without cracking or breaking, making them suitable for applications that experience rapid heating and cooling cycles.
3. Chemical stability: Magnesia refractories are chemically stable and do not react with most chemicals, which makes them suitable for use in corrosive environments.
Magnesia refractories are commonly used in industries such as steelmaking, cement manufacturing, glass production, and petrochemical refining. They are used to line furnaces, ladles, tundishes, converters, and other high-temperature equipment where they provide superior thermal insulation and resistance to chemical corrosion.
