Magnesia bricks are refractory materials made primarily from magnesium oxide, which is derived from natural magnesite or synthetic sources. These bricks are known for their high melting point, excellent thermal stability, and resistance to corrosion, making them ideal for high-temperature applications. They are typically used in environments that require durability and resistance to chemical attack, such as furnaces, kilns, and incinerators.
| Material Composition | Magnesium oxide (MgO) |
| Density | 2.5 to 3.0 g/cm³ |
| Temperature Resistance | Up to 1800°C (3272°F) |
| Alumina Content | Typically less than 5% |
| Size Range | Standard sizes include 230x114x76 mm and 305x305x76 mm |
When selecting magnesia bricks, buyers should consider the specific application and the operating temperature conditions. It's important to specify the desired density, thermal conductivity, and any required certifications for the materials used. Additionally, buyers should communicate the quantity needed, as larger orders may influence pricing and availability.
