Thermal Stability of Transition Phases in Zirconia-Doped Alumina
Alumina was prepared from aqueous salt solution by homogeneous precipitation followed by calcination in air. The dependence of the thermal stability of the transition phases on the presence of zirconia dopart and on autoclave treatment was investigated. thermal stability was increased by each of these parameters, and the greatest increase occurred with both parameters in combination to produce theta-alumina that withstood in at 1200*C without transformation to alpha-alumina. This material has potential for applications in high-temperature catalysis.
