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