Alumina hollow ball is a new type of high temperature insulation material which is made from industrial aluminum treated by smelting in an electric furnace. The crystal form is a-Al2O3 micro crystals.
Alumina hollow ball can be made into various shpes with the highest temperature ***0 ℃, which is of high mechanical strength, and the volume density is only one-half of corundum products.
There are mixed grade alumina hollow ball and graded ball two types: mixed-level ball diameter is 0.**5mm, graded ball diameters can be respectively 0.**1mm, **2mm, **3mm, **5mm.
Application:
Alumina hollow balls are widely used in high temperature furnace
and ultra high temperature furnaces such as the petrochemical
industry gasifier reactor, carbon black industry, metallurgical
industry and other high-temperature induction furnaces, etc.
