Calcined Bauxite is a premium-grade aluminum ore that has undergone sophisticated high-temperature treatment, ranging from 1,000 to 1,600 degrees Celsius. This meticulous process, known as calcination, effectively purges moisture and volatile components, significantly enhancing the bauxite's physical characteristics. The result is a material optimally suited for a wide spectrum of industrial applications, setting a new standard in performance.
Key Features:
High Aluminum Oxide Content: With a remarkable alumina (Al2O3) concentration of approximately 75-90%, calcined bauxite stands as a superior source of aluminum.
Thermal Stability: Post-calcination, the material exhibits exceptional resistance to extreme temperatures and thermal shock, making it an indispensable choice for refractory applications.
Hardness: Exhibiting outstanding hardness and abrasion resistance, it is the ideal material for manufacturing highly durable, wear-resistant products.
Chemical Resistance: As a chemically inert material, it provides formidable resistance against acids, alkalis, and various corrosive agents.
Density: The calcination process significantly enhances the density of the bauxite, boosting its effectiveness in demanding heavy-duty applications.
Applications:
Refractories: Integral in the production of firebricks, furnace linings, and various high-temperature-resistant materials, ensuring longevity and reliability.
Abrasives: Leveraging its hardness, calcined bauxite is a core component in manufacturing advanced grinding materials, sandblasting media, and precision cutting tools.
Road Surfacing (Skid Resistance): Its superior wear resistance makes it an ideal choice for creating anti-skid surfaces, particularly in high-traffic roadways to ensure safety.
Cement and Steel Industries: Utilized in the formulation of high-alumina cement and as a critical flux in the steel-making process, enhancing efficiency and product quality.
Ceramics: Essential as a raw material in the creation of high-quality ceramic products, contributing to the durability and finish.
Overall, calcined bauxite is an extraordinarily versatile material, serving industries that demand unparalleled durability, exceptional thermal resistance, and robust chemical inertness.
The product parameters of calcined bauxite vary depending on the grade and the unique industrial requirements. Below are the distinguished parameters that are typically considered when evaluating calcined bauxite for a variety of 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 precisely adjusted based on specific application requirements, and the various grades of calcined bauxite can be expertly tailored to meet distinct industrial uses such as refractory materials, road surfacing, or abrasives.
