Types of Magnesia Refractory Bricks
Magnesite bricks are mainly made from natural magnesite materials, with a magnesium oxide content of over 89%. The melting point of magnesite is as high as 2800ºC, making bricks highly refractory. Depending on the production process and properties, magnesia bricks are 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. |
