Read OnT-162 Tabular Alumina Balls are high-purity sintered alpha-alumina spheres (in various sizes). This product has been fired at extremely high temperatures (>1900°C) to reduce porosity to a very low level. This high-temperature process leads the growth of large plate-like (or tablet-like) alpha-alumina crystals giving "tabular" alumina its name.

Read Onspecific temperatures. Alpha alumina (α- Al 2 O 3) is the most stable and is created when the aluminum oxide is annealed to at least 1100C.° This crystalline structure can be used as a dielectric device due to the structure of its molecules. This allows electron tunneling to be limited when the device is turned off

Read On1. Introduction. In general, alumina exists in various types of polymorphs, such as α, γ, θ, κ, and η [1,2].As compared to other transition phases, alpha alumina (α-Al 2 O 3) has been widely applied in numerous fields such as refractories, abrasives, special ceramics and light-emitting diode-based displays due to its good thermal stability, high mechanical strength, …
Read OnTabular Alumina Balls BASF T-162 Tabular Alumina Balls® are sintered alpha alumina with very high-purity. The alumina is form of pure aluminum oxide which has been fired at such high temperatures (well over 1900°C) that practically all porosity and shrinkage is removed. It is essentially 100 percent alpha alumina (corundum).
Read OnTabular Alumina Balls. Tabular Alumina Balls are sintered alpha alumina with very high-purity, high-density, fully shrunk, coarse crystalline alpha aluminas. When the internal crystalline structure of tabular alumina is examined, large plate-like or tablet-like crystals are apparent. The shape of these crystals gives "tabular" alumina its name.
