Calcined Bauxite is an exceptional high-grade aluminum ore, meticulously heat-treated at elevated temperatures ranging from approximately 1,000 to 1,600 degrees Celsius. This sophisticated process, termed calcination, effectively eliminates moisture and volatile substances, significantly enhancing the physical attributes of the bauxite. As a result, it becomes highly suitable for a myriad of industrial applications, offering unparalleled performance and reliability.
Key Features:
High Aluminum Oxide Content: Calcined bauxite is renowned for its substantial alumina content, typically comprising around 75-90% alumina (Al2O3), establishing itself as an excellent and rich source of aluminum.
Thermal Stability: The calcination process imparts remarkable thermal resistance and stability, making the material exceedingly resistant to high temperatures and thermal shock. This characteristic renders it perfect for a wide range of refractory applications.
Hardness: With outstanding hardness and superior abrasion resistance, calcined bauxite proves to be a robust and durable material, ideal for wear-resistant products that require longevity and resilience.
Chemical Resistance: This material showcases incredible chemical inertness, providing excellent resistance against acids, alkalis, and other corrosive substances, ensuring longevity and reliability.
Density: The process of calcination enhances the density of the bauxite, which greatly improves its performance and effectiveness in demanding heavy-duty applications.
Applications:
Refractories: Calcined bauxite is integral in the production of firebricks, furnace linings, and various other products designed to withstand extreme temperatures.
Abrasives: Thanks to its exceptional hardness, calcined bauxite is a preferred choice in manufacturing grinding materials, sandblasting media, and precision cutting tools.
Road Surfacing (Skid Resistance): Its superior wear resistance makes calcined bauxite a sought-after material for creating anti-skid surfaces on high-traffic roadways, ensuring safety and durability.
Cement and Steel Industries: It plays a crucial role in the formulation of high-alumina cement and serves as a beneficial flux in the steel production process.
Ceramics: Calcined bauxite is employed as a fundamental raw material in crafting a diverse array of ceramic products, contributing to their strength and quality.
Overall, calcined bauxite stands out as an incredibly versatile material, highly esteemed across industries that demand exceptional durability, thermal resistance, and chemical inertness. Its wide range of applications speaks to its reliability and indispensability in modern industrial processes.
The refined specifications of our calcined bauxite vary meticulously with the specific industrial demands and grading criteria. Listed below are the quintessential parameters that are meticulously assessed when appraising calcined bauxite for a myriad 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 specifications may be precisely adjusted in alignment with particular application essentials, allowing various grades of calcined bauxite to be custom-fitted for specialized uses, including refractory materials, road surfacing solutions, and abrasives.
