Introduction to Magnesia Bricks
Magnesia bricks are a type of refractory material that is primarily composed of magnesium oxide (MgO). They are widely used in high - temperature industrial applications due to their excellent refractory properties. Magnesia bricks have high melting points, usually above 2800°C, which allows them to withstand extremely high temperatures without significant deformation or melting. They also possess good thermal shock resistance and chemical stability, making them suitable for use in environments where they are exposed to corrosive substances, such as slags and gases, in industries like steelmaking, non - ferrous metal smelting, and cement production.
