Calcined Bauxite is a premium aluminum ore, meticulously treated at soaring temperatures, ranging from 1,000 to 1,600 degrees Celsius. This heat-intensive process, known as calcination, effectively eradicates moisture and volatile components, thereby elevating the physical properties of the bauxite to meet the demanding standards of diverse industrial applications.
Key Features:
High Aluminum Oxide Content: Calcined bauxite is renowned for its rich alumina (Al2O3) content, usually ranged between 75-90%, making it an exceptional source of aluminum.
Thermal Stability: Post-calcination, the material showcases remarkable resistance to extreme temperatures and sudden thermal shocks, positioning it as a perfect candidate for refractory applications.
Hardness: Known for its outstanding hardness and resilience against abrasion, calcined bauxite is a robust option for wear-resistant products.
Chemical Resistance: This material is chemically inert, providing formidable resistance to acids, alkalis, and other corrosive agents.
Density: The calcination process significantly enhances the density of bauxite, boosting its performance in strenuous, heavy-duty applications.
Applications:
Refractories: Integral in the production of firebricks, furnace linings, and other products designed to withstand high temperatures.
Abrasives: With its inherent hardness, calcined bauxite is indispensable in crafting grinding materials, sandblasting media, and precision cutting tools.
Road Surfacing (Skid Resistance): Its superior wear resistance renders it a preferred material for skid-resistant surfaces on bustling roadways.
Cement and Steel Industries: Employed in high-alumina cement production and as a flux in the intricate steel-making process.
Ceramics: Utilized as a foundational raw material in the creation of various ceramic products.
Overall, calcined bauxite stands out as a remarkably versatile material, serving industries that demand high durability, thermal resilience, and chemical inertness.
The product parameters of calcined bauxite vary depending on the grade and specific industrial requirements. Below we present the quintessential parameters considered in evaluating calcined bauxite for a myriad of high-performance 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 can be adapted based on specific application requirements, with different grades of calcined bauxite tailored to meet specialized industrial needs such as refractory materials, road surfacing, or abrasive applications.
