Ceramic Alumina Bubble Balls include alumina bubble ball, regenerated alumina bubble ball and stabilized zirconia bubble ball. Alumina bubble ball and its products are lightweight refractories with high temperature resistance and excellent energy saving. They are very stable in high temperature atmosphere. It is especially suitable for high temperature kilns of 1600-2400 ℃. The alumina bubble ball produced by our company has small bulk density and low thermal conductivity. It is an ideal high temperature, ultra-high temperature insulation filler, high temperature refractory concrete lightweight material, high temperature pouring material, etc. In addition, it can also be used in high temperature energy saving down flame kiln, shuttle kiln, molybdenum wire furnace, tungsten rod furnace, induction furnace, nitriding furnace, etc. It can save more than 40% energy, and the energy saving effect is remarkable.
