What Are Hollow Alumina Balls Mainly Used For?

Hollow alumina balls are a high-temperature insulation material that can be made into various refractory and insulation products. The maximum use temperature is 1800℃. The products have high mechanical strength and low volume density. They are lightweight, hard, high temperature resistant, and corrosion resistant. The following will introduce some of the main applications of hollow alumina balls.

1. Hollow alumina balls are widely used in the field of filling materials

Because hollow alumina balls have a low specific gravity and low thermal conductivity, they have good insulation properties, and can effectively reduce heat conduction and improve insulation effects, so they are often used in various insulation products, such as insulation surface layers, insulation wall panels, and insulation pipes.

2. Alumina hollow balls are also used to prepare lightweight materials

Because alumina hollow balls have the characteristics of low volume density and high compressive strength, they are often used to make fillers for some lightweight composite materials. While reducing the weight of the product, the strength can also be guaranteed. By mixing alumina hollow balls with other basic materials (such as polymers, rubber, etc.), lightweight composite materials such as automotive parts, aerospace components, and sports equipment can be prepared.

3. Alumina hollow balls can also be used to prepare high-temperature and corrosion-resistant materials

Because the maximum use temperature of alumina hollow balls can reach 1800℃, it has high refractoriness. At the same time, it also has corrosion resistance, so it is often used to make some refractory materials, and ceramic products, such as alumina hollow ball bricks, alumina hollow ball castables, and other products.

4. Alumina hollow balls can also be used in the field of environmental protection

Because alumina hollow balls have good adsorption properties, they can adsorb various pollutants and harmful gases. Therefore, it is often used as exhaust gas purification equipment, oil pollution treatment materials water treatment agents, etc.

Alumina hollow balls have a wide range of applications and are widely used in metallurgy, aerospace, coal, chemical, and other industries. In the field of high-temperature industrial kilns, they are mainly used in the production of refractory bricks and castables.
