Calcined Bauxite is an exceptional, high-grade aluminum ore that undergoes a transformative heat-treatment process at temperatures ranging from 1,000 to 1,600 degrees Celsius. This specialized procedure, known as calcination, effectively eliminates moisture and volatile impurities, significantly enhancing the bauxite's physical properties. The result is a superior material, optimized for a wide array of industrial applications.
Key Features:
High Aluminum Oxide Content: Calcined bauxite boasts an impressive alumina (Al2O3) concentration, typically ranging from 75-90%, establishing it as a prime source of aluminum.
Thermal Stability: The calcination process imparts remarkable thermal stability and resistance to thermal shock, making this material an outstanding choice for demanding refractory applications.
Hardness: With its superior hardness and excellent abrasion resistance, calcined bauxite stands as a robust option for wear-resistant products.
Chemical Resistance: This material's chemically inert nature grants it exceptional resistance against acids, alkalis, and various corrosive substances.
Density: The calcination process enhances the density of bauxite, thereby boosting its performance in high-stress, heavy-duty applications.
Applications:
Refractories: Essential in crafting firebricks, furnace linings, and other high-temperature resistant products, ensuring longevity and reliability.
Abrasives: Thanks to its remarkable hardness, calcined bauxite is integral in manufacturing grinding materials, sandblasting media, and precise cutting tools.
Road Surfacing (Skid Resistance): Its exceptional wear resistance makes it the material of choice for anti-skid surfaces, particularly in high-traffic roadways, enhancing safety.
Cement and Steel Industries: Utilized in producing high-alumina cement and as a crucial flux component in the steel-making process, ensuring quality and efficiency.
Ceramics: Serves as a vital raw material in the creation of various ceramic products, contributing to their strength and durability.
Overall, calcined bauxite is a remarkably versatile material, indispensable in industries that demand exceptional durability, thermal resistance, and chemical inertness.
The product parameters of calcined bauxite are tailored to meet diverse industrial specifications and vary with the grade. Below are the benchmark parameters typically assessed when considering calcined bauxite for distinct 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 guidelines can be adjusted per application-specific needs. Distinct calcined bauxite grades are custom-made to cater to varied industrial uses such as refractory materials, road surfacing, and abrasives.
