Calcined Bauxite is a premium, high-grade aluminum ore that undergoes heat treatment at elevated temperatures, ranging from 1,000 to 1,600 degrees Celsius. This meticulous process, known as calcination, effectively removes moisture and volatile components, enhancing the bauxite's physical properties. Consequently, this makes it exceptionally suitable for a wide array of demanding industrial applications.
Key Features:
High Aluminum Oxide Content: Calcined bauxite is renowned for its impressive alumina content of approximately 75-90%, making it an outstanding source of aluminum.2O3), making it an excellent source of aluminum.
Thermal Stability: Post-calcination, the material exhibits remarkable resistance to intense heat and thermal shock, rendering it perfect for refractory applications.
Hardness: With its superior hardness and abrasion resistance, it stands out as a highly durable material for wear-resistant applications.
Chemical Resistance: This chemically inert material ensures robust resistance against acids, alkalis, and various corrosive agents.
Density: The calcination process significantly enhances the density of bauxite, thereby boosting its performance in heavy-duty industrial applications.
Applications:
Refractories: Essential in crafting firebricks, furnace linings, and other products that demand exceptional high-temperature resistance.
Abrasives: Its intrinsic hardness makes calcined bauxite ideal for manufacturing grinding materials, sandblasting media, and precision cutting tools.
Road Surfacing (Skid Resistance): Its formidable wear resistance makes it a preferred choice for anti-skid surfaces in bustling roadways.
Cement and Steel Industries: Integral in high-alumina cement production and serves as a crucial flux in the steel-making process.
Ceramics: Functions as a vital raw material in crafting diverse ceramic products.
Overall, calcined bauxite is a remarkably versatile material, coveted across industries that demand high durability, exceptional thermal resistance, and immense chemical inertness.
The product parameters of calcined bauxite are critical and can vary based on the grade and precise industrial needs. Below, we highlight the typical parameters that professionals consider indispensable when assessing calcined bauxite for a multitude 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 are adaptable, allowing for customization to specific application requirements. Different grades of calcined bauxite can be expertly tailored to suit particular industrial uses, such as refractory materials, road surfacing, or as abrasives, ensuring optimal performance across various sectors.
