Product Description of Refractory Alumina Bubble Balls
Alumina Bubble Balls is produced from high-purity alumina in an electric arc furnace. Once melted, the alumina is atomized with compressed air, which produces hollow spheres. The melting point of Bubble Alumina is approximately 2100ºC. The hollow spheres are chemically inert and have very low bulk density, extremely low thermal conductivity, high hardness, high wear-resistance, and superior insulating properties.
Alumina Bubble Balls or Alumina Hollow Balls are known for their distinctive properties that make them suitable for a range of applications.
1.Lightweight: The hollow structure of these balls makes them remarkably lightweight, offering potential savings in terms of transport and handling costs.
2.High Thermal Resistance: They have exceptional thermal resistance, making them suitable for applications involving high temperatures.
3.High Mechanical Strength: Despite their lightweight structure, Alumina Hollow Balls have excellent mechanical strength, offering long-term durability.
4.Chemical Resistance: They resist most acids and alkalis, making them ideal for applications in harsh chemical environments.
Applications of Alumina Hollow Balls
The versatile properties of Alumina Hollow Balls have led to their widespread use across numerous industries.
Refractories: Due to their high thermal resistance, Alumina Hollow Balls are used in refractories, including fire-resistant bricks and monolithic refractories.
Ceramics: In the ceramics industry, they are used for producing lightweight, heat-resistant products.
Insulation: They are an excellent insulator, used in thermal insulation materials and products.
Chemical Industry: Owing to their chemical resistance, these balls find applications in various chemical processes.
