Product Description Product DescriptionChina Supplier High Quality/ High Purity Tabular Alumina Sintered Alumina White Tabular Alumina For Ladle Refractory Bricks Tabular corundum, also known as sintered tabular alumina, is a high-purity form of alumina (Al2O3) that is specifically processed to have a unique tabular, or flat, shape. It is produced by sintering (heating without melting) high-grade alumina powder at temperatures above 1900°C, causing the alumina particles to grow and form large, flat, plate-like crystals.Tabular corundum offers several advantages in various industrial applications due to its distinctive properties: High Purity, Excellent Thermal Stability, High Mechanical Strength, Low Porosity, Dimensional Stability, etc.Overall, tabular corundum, or sintered tabular alumina, is highly valued for its purity, thermal stability, mechanical strength, and low porosity, making it a versatile material in various industrial applications, particularly in refractories and ceramics.BrandZhengzhou Xinli Wear-resistant Materials Co.

It is an excellent synthetic refractory raw material. Tabular corundum is used as Refractory aggregate can be used in combination with spinel, calcined activated alumina and binding agents such as cement, clay or resin. The prepared high-purity corundum bricks have low impurity content (such as SiO2), high bulk density and good thermodynamic properties, making corundum bricks Bricks are resistant to thermal, chemical and structural damage caused by the operation of gasifiers and other industrial furnaces.Advantages: high refractoriness; high corrosion resistance; high erosion resistance; high thermal shock resistance; high strength, good toughness; stable chemical properties; resistance to alkaline slag erosion, good resistance to slag erosion, and good resistance to molten iron erosion ; Resistant to erosion by molten steel and good air permeability.Application ScenariosTabular corundum, or sintered tabular alumina, finds application in a wide range of industries and processes due to its unique properties. Some of the key applications of tabular corundum include:Refractories: Tabular corundum is extensively used in the production of refractory materials, which are crucial for high-temperature applications. It is used as a raw material in the manufacturing of refractory bricks, monolithic refractories, and shaped refractory products. Its high purity, thermal stability, and mechanical strength make it ideal for lining furnaces, kilns, and other high-temperature equipment.Foundry and Investment Casting: Tabular corundum is employed in foundry applications, particularly in investment casting processes. It is used as a filler material in ceramic shells, which are used to create intricate metal castings. The high dimensional stability and low porosity of tabular corundum help in achieving precise and detailed castings with minimal defects.Ceramics Manufacturing: Tabular corundum serves as a raw material in the production of advanced ceramics. It is used in ceramic formulations to enhance properties such as mechanical strength, thermal shock resistance, and wear resistance. The high-purity and controlled particle size distribution of tabular corundum contribute to the quality and performance of ceramic materials.Abrasives and Polishing: Tabular corundum is employed as an abrasive material in various applications. It is used in grinding wheels, sandpaper, and other abrasive products for the cutting, grinding, and polishing of metals, ceramics, glass, and other materials. The hardness and durability of tabular corundum make it effective for material removal and surface finishing.Catalyst Supports: Tabular corundum is used as a support material for catalysts in chemical and petrochemical processes. Its high surface area and thermal stability make it suitable for carrying and dispersing catalytic agents, enhancing the efficiency of chemical reactions.Insulation Materials: The superior thermal stability and low thermal conductivity of tabular corundum make it suitable for high-temperature insulation applications. It is used as an insulation material in furnaces, kilns, and other thermal processing equipment, helping to minimize heat loss and improve energy efficiency.Electronics and Semiconductor Industry: Tabular corundum is utilized in the fabrication of substrates and components for the electronics and semiconductor industries. Its high purity and thermal stability make it suitable for use in applications such as high-temperature insulating tubes, heaters, and electrical insulators.These are just a few examples of the applications of tabular corundum. Its unique combination of high purity, thermal stability, mechanical strength, and low porosity make it a valuable material in various industries that require reliable performance under extreme conditions.Recommend ProductsCustomer's FeedbackCompany ProfileZhengzhou Xinli Wear-resistant Materials Co.
