Calcined Bauxite is a high-grade aluminum ore that has been heat-treated at high temperatures, typically around 1,000 to 1,600 degrees Celsius, in order to remove moisture and volatile substances. This process, known as calcination, enhances the physical properties of the bauxite, making it more suitable for various industrial applications.
Key Features:
High Aluminum Oxide Content: Calcined bauxite typically contains around 75-90% alumina (Al2O3), making it an excellent source of aluminum.
Thermal Stability: After calcination, the material becomes highly resistant to high temperatures and thermal shock, making it ideal for use in refractory applications.
Hardness: It possesses excellent hardness and abrasion resistance, which makes it a durable material for wear-resistant products.
Chemical Resistance: The material is chemically inert, offering resistance to acids, alkalis, and other corrosive substances.
Density: The calcination process increases the density of the bauxite, which improves its performance in heavy-duty applications.
Applications:
Refractories: Used in the manufacturing of firebricks, furnace linings, and other high-temperature-resistant products.
Abrasives: Due to its hardness, calcined bauxite is used in the production of grinding materials, sandblasting media, and cutting tools.
Road Surfacing (Skid Resistance): Its high wear resistance makes it a popular choice for anti-skid surfaces in high-traffic roadways.
Cement and Steel Industries: It is used in high-alumina cement and as a flux in the steel-making process.
Ceramics: Serves as a raw material in the production of ceramic products.
Overall, calcined bauxite is a versatile material with applications in industries requiring high durability, thermal resistance, and chemical inertness.
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 adjusted based on specific application requirements, and different grades of calcined bauxite can be tailored to fit particular industrial uses like refractory materials, road surfacing, or abrasives.
