Product type
High alumina bricks are refractory materials made primarily from alumina, which is a high-purity aluminum oxide. These bricks are known for their excellent thermal stability, low thermal conductivity, and resistance to chemical corrosion. They are typically manufactured through a process of pressing and firing at high temperatures, resulting in a dense and durable product suitable for extreme environments.
| Alumina content | Typically 50% to 90% |
| Temperature resistance | Up to 1800°C (3272°F) |
| Density | 2.5 to 3.0 g/cm³ |
| Thermal conductivity | 0.15 to 0.25 W/m·K |
| Compressive strength | Up to 150 MPa |
When selecting high alumina bricks, consider the alumina content required for your application, as higher alumina bricks offer better performance at elevated temperatures. Additionally, specify the desired temperature resistance, density, and any relevant certifications for your industry. It's also important to indicate the quantity needed, as this can affect pricing and availability.
