Calcined Bauxite, a premium grade aluminum ore, undergoes a meticulous heat-treatment process at elevated temperatures ranging from 1,000 to 1,600 degrees Celsius. This transformative process, known as calcination, effectively removes moisture and volatile substances, significantly enhancing the bauxite's physical attributes. As a result, it becomes exceptionally well-suited for a variety of demanding industrial applications.
Key Features:
High Aluminum Oxide Content: With a substantial alumina (Al2O3) content of approximately 75-90%, calcined bauxite stands as an outstanding aluminum source.
Thermal Stability: Post-calcination, the material exhibits remarkable resistance to extreme temperatures and thermal shock, making it perfect for refractory use.
Hardness: Renowned for its superior hardness and abrasion resistance, this material ensures exceptional durability for wear-resistant products.
Chemical Resistance: Demonstrating chemical inertness, it provides robust resistance against acids, alkalis, and various corrosive substances.
Density: The calcination process significantly boosts the bauxite's density, enhancing its performance in heavy-duty industrial settings.
Applications:
Refractories: Integral in the production of firebricks, furnace linings, and other products designed for high temperatures.
Abrasives: Its impressive hardness makes it an ideal choice for manufacturing grinding materials, sandblasting media, and cutting tools.
Road Surfacing (Skid Resistance): Thanks to its high wear resistance, it is favored for anti-skid surfaces on high-traffic roads.
Cement and Steel Industries: Utilized in crafting high-alumina cement and as a flux component in steel production.
Ceramics: Acts as a crucial raw material in the manufacturing of a wide array of ceramic products.
Overall, calcined bauxite is a highly adaptable material, indispensable in industries that demand exceptional durability, thermal resistance, and chemical inertness.
The product parameters of calcined bauxite vary depending on the grade and specific industrial requirements. Below are typical parameters that are considered when evaluating calcined bauxite for various applications:
| Alumina (Al2O3) | 75% - 90% | Higher alumina content increases its suitability for refractories and abrasives. |
| Silica (SiO2 ) | 1% - 10% | Lower silica content is preferable for refractory use to minimize melting at high temperatures. |
| Iron Oxide (Fe2O3) | 1% - 5% | Higher iron oxide content is acceptable for some abrasive applications but less desirable in refractories. |
| Titania (TiO2) | 1% - 4% | Impacts refractoriness and heat resistance. |
| Calcium Oxide (CaO) | 0.3% - 0.6% | Minimal calcium oxide is preferred to avoid fluxing and lowering the material's refractory properties. |
| Magnesia (MgO) | 0.1% - 0.5% | Small amounts help improve sintering in refractory applications. |
| Moisture | 0.5% - 1.5% | Low moisture content is necessary for stability and performance, especially in high-temperature settings. |
| Bulk Density | 2.8 - 3.3 g/cm³ | Higher density provides better thermal and mechanical properties. |
| Porosity | 5% - 10% | Low porosity is preferred for refractories to enhance thermal resistance. |
| Grain Size | Varies depending on application | For refractory materials: typically between 0-50 mm. For abrasives: typically finer, ranging from 1 mm to 8 mm. |
| Hardness | 8 - 9 on the Mohs scale | Ensures durability and abrasion resistance. |
| Melting Point | Above 1,600°C | Ensures high thermal stability and performance in extreme heat conditions. |
These parameters may be adjusted based on specific application requirements, allowing customization for industrial uses such as refractory materials, road surfacing, or abrasives tailored to fit particular demands.
