Alumina bubble is a new type of high-temperature insulation materials, it is the industrial alumina smelting in the electric furnace and blowing, the crystal form is microcrystal of a-Al2O3. The main body can be made into various shapes. it’s mechanical strength are several times for the general light weight products, while the bulk density is only one-half of corundum products.
Typical Applications:
Bright Annealing Furnace (for stainless steel, non-ferrous alloy metal), Metal Ceramic Sintering Furnace, Brazing Furnace, Semiconductor Firing Furnace and Hydrogen Atmosphere Furnace.
