Summary

In order to produce nanocrystalline ceramics, which is amenable to deformation processing, a “Combustion Assisted Process (CAP)”, using metal-nitrate as the oxidizer and urea as the fuel was investigated. The paper reports on the results of the characterization prcedure on the as synthesized α-alumina and alumina-zirconia composites. As determined by X-Ray diffraction (XRD), and transmission electron microscopy (TEM), the average particle size of α-alumina was determined to be 40nm while the tetragonal-zirconia particles were slightly smaller.
