Advantage
Zhicheng Industry is a company specializing in the production and sales of alumina and its products. The product alumina hollow ball brick is fired at a high temperature of 1750 degrees, which is a kind of energy-saving and thermal insulation material for very high-temperature materials.
Alumina hollow spheres (3/5mm)
Alumina hollow spheres 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 α-Al2O3 microcrystal. Using alumina hollow spheres as the main body, various specifications of refractory lightweight products can be made. The maximum use temperature is up to 1800℃, with high mechanical strength, low thermal conductivity, and stable performance under various atmospheres.
Alumina hollow spheres (2/3mm)
Alumina hollow spheres 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 α-Al2O3 microcrystal. Using alumina hollow spheres as the main body, various specifications of refractory lightweight products can be made. The maximum use temperature is up to 1800℃, with high mechanical strength, low thermal conductivity, and stable performance under various atmospheres.
