Calcined Bauxite is a superior-grade aluminum ore that undergoes a specialized heat treatment process at soaring temperatures, typically ranging from 1,000 to 1,600 degrees Celsius. This meticulous calcination procedure effectively eliminates moisture and volatile substances, thereby significantly enhancing the bauxite's inherent physical properties. As a result, it becomes exceptionally suited for an array of industrial applications, fulfilling diverse and demanding requirements.
Key Features:
High Aluminum Oxide Content: Boasting an impressive alumina (Al2O3) content, Calcined Bauxite typically comprises around 75-90%, establishing itself as a premium source of aluminum.
Thermal Stability: Through the process of calcination, the material achieves remarkable resistance to elevated temperatures and thermal shock, rendering it perfect for application in refractory contexts.
Hardness: Renowned for its superior hardness and abrasion resistance, it serves as an indispensable material for crafting durable, wear-resistant products.
Chemical Resistance: Characterized by its chemically inert nature, this material provides robust resistance against acids, alkalis, and other corrosive agents.
Density: The rigorous calcination process considerably increases the density of the bauxite, thereby enhancing its effectiveness in demanding, heavy-duty applications.
Applications:
Refractories: Integral in the production of firebricks, furnace linings, and a variety of high-temperature-resistant products.
Abrasives: Thanks to its notable hardness, calcined bauxite is a preferred choice in creating grinding materials, sandblasting media, and precision cutting tools.
Road Surfacing (Skid Resistance): Its outstanding wear resistance makes it an ideal selection for anti-skid surfaces on high-traffic roadways, ensuring safety and longevity.
Cement and Steel Industries: Employed in crafting high-alumina cement formulations and as a crucial flux in the steel-making process.
Ceramics: Functions as a key raw material in the manufacturing of diverse ceramic products.
Overall, calcined bauxite emerges as a versatile powerhouse, with applications across industries that demand exceptional durability, thermal resilience, and chemical inertness. Its multifaceted utility continues to support innovations across various sectors.
The product parameters of calcined bauxite vary depending on the grade and specific industrial requirements. Below are typical parameters that are considered when evaluating calcined bauxite for various 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 exquisitely adjusted based on your specific application requirements, allowing different grades of calcined bauxite to be meticulously tailored for particular industrial uses, such as refractory materials, road surfacing, or abrasives.
