Alumina hollow sphere is a new type of high-temperature insulation material. It is made of industrial alumina by melting and blowing in an electric furnace. The crystal form is a-Al2O3 microcrystals. With alumina hollow sphere as the main body, it can be made into various shapes of products with a maximum use temperature of 1800℃. The products have high mechanical strength, which is several times that of general lightweight products, and the volume density is only half of that of corundum products.

Alumina hollow spheres are of two types: mixed-grade spheres and graded spheres: the particle size of mixed-grade spheres is 0.2-5mm, and the particle sizes of graded spheres are 0.2-1mm, 1-2mm, 2-3mm, and 3-5mm respectively.

It is widely used in high-temperature and ultra-high-temperature kilns such as petrochemical gasification furnaces, carbon black industrial reactors, and metallurgical induction furnaces, and has achieved very satisfactory energy-saving effects.
