Types of Magnesia Refractory Bricks
Magnesite bricks are mainly made from natural magnesite materials, and their magnesium oxide content exceeds 89%. Because of this high purity, they exhibit excellent thermal stability. Moreover, the melting point of magnesite is as high as 2800ºC, which means that these bricks are highly refractory and suitable for use in extremely high-temperature environments. Depending on the production process as well as the specific material properties, magnesia bricks can be divided into the following types:
| Types | Features | |
| Ordinary Magnesia Brick | Burned Magnesite Refractory Bricks; Chemically Bonded Magnesium Bricks; High Purity Magnesia Brick; Fused Magnesia Brick. |
Strong resistance to alkaline slag erosion; High thermal conductivity; High refractoriness; The higher the MgO content and the firing temperature, the better the gas erosion resistance and high-temp resistance. |
| Magnesium Aluminum Brick | Magnesia Alumina Spinel Brick; Fused And Bonded Magnesia Bricks; Magnesia-Silica Bricks; Forsterite Bricks. |
High temperature resistance; High strength; Good thermal shock stability; Strong corrosion resistance; Good volume stability; Environmentally friendly and chrome-free; Good peeling resistance. |
| Magnesia Carbon Brick | / | Good high temperature resistance; Strong slag resistance; Good thermal shock resistance; Low high temperature creep. |
| Magnesia Chrome Brick | Direct Bonded Magnesia Chrome Bricks; Semi-Rebonded Magnesia Chrome Bricks; Electro-Fused Rebonded Magnesia Chrome Bricks. |
High refractoriness; High high temperature strength; Strong resistance to alkaline slag erosion; Excellent thermal stability; Certain adaptability to acidic slag. |
