Alumina hollow ball products
Aluminum oxide hollow sphere products have the advantages of good thermal efficiency and light bulk density, and are widely used in high-temperature thermal equipment for chemical, ceramic, and national defense research. They are used to build the lining of high-temperature and ultra-high electric furnaces and kilns to reduce the weight of the furnace body, greatly improve thermal efficiency, shorten production cycles, and are ideal refractory materials for energy conservation and high efficiency.
