Abstract

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 dopant 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 1h at 1200 C without transformation to alpha-alumina. This material has potential for applications in high-temperature catalysis.
