Product profile:
Alumina Hollow Ball is a new kind of heat insulation material, it is used in the eaf melting in industrial aluminum and blowing, crystal - for Al2O3 nanocrystal. In alumina bubble can be made for the subject, the use of various shapes, the highest temperature 1800 ° c, the products of high mechanical strength, for general light products, and the number of times the volume density is only one half of corundum products. Therefore, in the gasifier, petrochemical industry, metallurgy industry, carbon industry reactor furnace temperature, such hi-temp extensively, made satisfactory effect in energy saving.
