The sintering behavior of alumina-zirconia powders prepared from inorganic precursors by a simple sol-gel process (Montanaro and Guilhot, 1989) with gel precipitation followed by peptization and consequent spraying of the sol through a nozzle to produce microspheres was studied by Negro and Montanaro (1996). Powders collected from such a process on calcination at 1200°C for 0.5 h produced porous microspheres. Hot pressing...
