Aluminum oxide hollow spheres are a type of hollow microsphere, with the main component of the sphere wall being aluminum oxide. Aluminum oxide hollow spheres have the characteristics of light weight, high temperature resistance, high strength, and good electrical insulation performance. At present, the processes for preparing hollow alumina balls include slurry spraying, coating spraying foaming, melt spraying, rolling ball method, etc. The insulation material prepared using alumina hollow spheres as lightweight skeleton materials is called lightweight alumina hollow sphere products. The following introduces the performance characteristics and production process of alumina hollow spheres.
Aluminum oxide hollow spheres have the characteristics of low shrinkage rate during heavy burning, high load softening temperature, high operating temperature, and high compressive strength. They can not only be used as insulation layers and come into direct contact with flames, but also have abundant raw materials and high cost-effectiveness. They are considered to be the most promising high-temperature insulation materials today. It has been widely used in high-temperature and ultra-high temperature kilns such as gasification furnaces in the petrochemical industry, carbon black industrial reaction furnaces, and induction furnaces in the metallurgical industry, achieving very satisfactory energy-saving effects.
