Aluminum oxide and alumina ceramics have excellent wear characteristics, chemical resistance, compressive strength, high-temperature properties, and dielectric strength. They are used widely because of their versatility and low cost. Their main drawback is its relatively poor thermal-shock resistance due to higher coefficients of thermal expansion and lower thermal conductivity (compared to other pure ceramic materials).

How is an Alumina Bubble Made?. Hollow insulating spheres made from high purity alumina are often referred to as bubble alumina or alumina bubbles. Fused bubble alumina is made when the raw materials (high purity Bayer process alumina) are heated to an extremely high heat (2000°C) in an electric arc furnace. The molten material is then poured out of the furnace and fed through a high pressure air stream. The stream of molten particles cools rapidly as it hits the air. The surface tension causes...
