Calcined Bauxite emerges as a premium-grade aluminum ore, meticulously refined through a rigorous heat-treatment process. Subjected to searing temperatures, ranging from 1,000 to 1,600 degrees Celsius, this transformative procedure-known as calcination-effectively expels moisture and volatile components. The result? A bauxite of unparalleled quality, primed to excel in an array of industrial applications, thanks to its enhanced and robust physical properties.
Key Features:
High Aluminum Oxide Content: Calcined bauxite boasts an impressive alumina (Al2O3) concentration, typically ranging from 75-90%, solidifying its status as a premier source of aluminum.
Thermal Stability: Post-calcination, the material exhibits exceptional resistance to high temperatures and thermal shocks, making it the ideal choice for refractory applications.
Hardness: Renowned for its outstanding hardness and abrasion resistance, this bauxite stands out as a top-tier choice for wear-resistant products.
Chemical Resistance: Its chemically inert nature provides robust resistance against acids, alkalis, and other corrosive entities.
Density: The calcination process significantly boosts the density of bauxite, thereby enhancing its efficacy in demanding, heavy-duty applications.
Applications:
Refractories: A key ingredient in manufacturing firebricks, furnace linings, and other products designed to withstand extreme temperatures.
Abrasives: Its inherent hardness makes calcined bauxite an essential component in creating superior grinding materials, sandblasting media, and precision cutting tools.
Road Surfacing (Skid Resistance): High wear resistance ensures its esteemed role in crafting anti-skid surfaces, especially vital for high-traffic roadways.
Cement and Steel Industries: Integral in the production of high-alumina cement and serves as a flux in the sophisticated steel-making process.
Ceramics: An indispensable raw material for the creation of exquisite ceramic products.
Overall, calcined bauxite epitomizes versatility, meeting the high standards of industries that demand unmatched durability, thermal resilience, and chemical inertness.
The product parameters for calcined bauxite can vary greatly based on the grade and distinct industrial needs. Below, discover the typical parameters that are crucial when assessing calcined bauxite for diverse 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 depending on specific application requirements. Different grades of calcined bauxite can be customized to meet the unique demands of various industries such as refractory materials, road surfacing, or abrasives.
