Buy high quality low price lightweight and highly efficient as insulating materials hollow alumina ball for refractory insulation at Wedge India. We offer excellent supply and installation service to achieve target performance results.

 

Hollow Alumina Balls are widely used for refractory insulation due to their excellent properties. They are primarily composed of high-purity alumina and have a hollow spherical structure, which makes them lightweight and highly efficient as insulating materials.

Properties of Hollow Alumina Balls:

High Thermal Insulation:

Low thermal conductivity helps in maintaining energy efficiency in high-temperature environments.

High-Temperature Resistance:

Can withstand temperatures typically above 1800°C.

Low Density:

Their hollow structure contributes to their lightweight nature, reducing the overall weight of the refractory system.

Good Mechanical Strength:

Despite being lightweight, they have significant strength, allowing them to be used in demanding conditions.

Chemical Stability:

Resistant to most chemical reactions, making them suitable for use in harsh environments.

 

Applications:

Refractory Linings:

  • Used in kilns, furnaces, and high-temperature reactors.

Thermal Insulation in Petrochemical Plants:

  • Ideal for processes involving high-temperature gases or liquids.

Catalyst Bed Support:

  • Used in catalytic converters as support media due to their thermal and chemical properties.

Steel and Ceramic Industries:

  • Suitable for high-temperature insulation in these sectors.

 

Benefits:

Energy Efficiency: Reduces heat loss, thereby saving energy costs.

Durability: Long-lasting performance even under cyclic thermal loads.

Eco-Friendly: Lightweight and reduces energy consumption.

 

If you are looking to source hollow alumina balls, it’s essential to consider their size, bulk density, and alumina content to match your specific application requirements.
