Steam-Enhanced Impurity Segregation in Dense Alumina
The concentration of Ca and Si on the external surface of dense polycrystalline alumina doped with CaO and SiO2was determined by Auger electron spectroscopy. After exposure to saturated steam, the Ca and Si concentrations were significantly higher and more dependent on the initial dopant concentration and firing time. By simultaneous doping with CaO and SiO2, it was possible to essentially reproduce the Ca and Si concentration profiles found at the surface of a commercial alumina.
