Alumina %
Alumina is produced by firing a tightly packed powder form of Al 2 O 3 which includes some binder material. Commercially available grades range from 90% up to % with the higher purity generating somewhat higher hardness. It is possible to machine alumina using diamond grinding techniques. Polishing is also possible, with the degree attainable affected by alumina grain size and production ...
Aluminum Oxide | Al2O3 Material Properties
Grinding media: General Information. Aluminum oxide, commonly referred to as alumina, possesses strong ionic interatomic bonding giving rise to it's desirable material characteristics. It can exist in several crystalline phases which all revert to the most stable hexagonal alpha phase at elevated temperatures. This is the phase of particular interest for structural appliions and the ...

Effect of grinding on the hydration of hydratable alumina ...
· Hydratable alumina (HA) is a superior Cafree refractory binder, but the quick hydration rate restricts the working time of castables bonded with HA. In this work, HA was grounded for 1 h and 6 h by a rotational ball mill to study the effect of grinding on the hydration of HA and properties of HAbonded castables. HA samples with and without grinding were cured at 30 °C and then terminated by ...
