High Quality hollow Alumina sphere

Alumina Bubble Balls Insulation Refractory Material

Product Description

hollow Alumina sphere is a new type of high-temperature heat insulation material, which is produced by smelting and blowing industrial alumina in an electric furnace, and the crystal form is a-Al2O3 microcrystal. Taking alumina hollow balls as the main body, it can be made into various shapes. The maximum operating temperature is 1800℃. The mechanical strength of the products is high, which is several times that of general light products, and the bulk density is only half of corundum products.


hollow Alumina sphere and its products are a kind of light-weight refractory material with high temperature resistance and excellent energy saving. hollow Alumina sphere is very stable in various atmospheres. Especially applied in high temperature kiln at 1800℃. Hollow spheres can be used as high-temperature, ultra-high-temperature insulation fillers, high-temperature refractory concrete lightweight aggregates, high-temperature castables, etc. Hollow ball brick can be used in high temperature energy saving (>30%) inverted flame kiln, shuttle kiln, molybdenum wire furnace, tungsten rod furnace, induction furnace, nitriding furnace, etc. For reducing the weight of the furnace body, transforming the structure, saving materials, and saving energy, obvious results will be achieved.
