Calcined Bauxite is a superior-grade aluminum ore that has been meticulously heat-treated at soaring temperatures, typically ranging from 1,000 to 1,600 degrees Celsius. This precise process, known as calcination, meticulously removes moisture and volatile substances, significantly enhancing the bauxite's physical properties, thereby rendering it exquisitely suitable for a diverse array of industrial applications.
Key Features:
High Aluminum Oxide Content: Calcined bauxite boasts an impressive alumina content, typically ranging between 75-90% Al2O3), establishing it as a remarkable source of aluminum.
Thermal Stability: Post calcination, the material exhibits exceptional resistance to elevated temperatures and thermal shock, rendering it perfectly suited for critical refractory applications.
Hardness: With outstanding hardness and unparalleled abrasion resistance, it proves to be an enduring material ideal for wear-resistant products.
Chemical Resistance: The material is inherently chemically inert, providing robust resistance to acids, alkalis, and other corrosive substances.
Density: The calcination process significantly augments the density of the bauxite, thereby enhancing its performance in demanding heavy-duty applications.
Applications:
Refractories: Essential in the creation of firebricks, furnace linings, and other high-temperature-resistant products, offering unmatched performance.
Abrasives: Thanks to its inherent hardness, calcined bauxite is pivotal in the production of superior grinding materials, efficient sandblasting media, and precision cutting tools.
Road Surfacing (Skid Resistance): Its outstanding wear resistance makes it a preferred choice for anti-skid surfaces in heavily trafficked roadways.
Cement and Steel Industries: Integral in high-alumina cement production and serves as a crucial flux in the steel-making process.
Ceramics: Plays a vital role as a foundational raw material in the creation of diverse ceramic products.
Overall, calcined bauxite is a phenomenally versatile material with widespread applications across industries demanding unparalleled durability, exceptional thermal resistance, and steadfast chemical inertness.
The product parameters of calcined bauxite are diverse and tailored to meet the precise industrial criteria and grade requirements. Presented below are the standard parameters essential for evaluating calcined bauxite across varied industrial 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 adjustable to meet specific application needs, allowing different grades of calcined bauxite to be precisely customized for specialized industrial uses such as refractory materials, road surfacing, or abrasive applications.
