Abstract
Coating of alumina powders with tetragonal zirconia grains in the nanometric size range was obtained from a modified zirconium n-propoxide sol.
Powder sedimentation observations and washing experiments were performed to show modifications of particles surface. Amorphous precursor film formation and crystalline zirconia coating were characterized by transmission electron microscopy. Crystallographic relationships between zirconia and alumina particles were also observed.
