X-RAY AND MICRO-RAMAN ANALYSIS OF NANOPHASE ZRO2 AND Y2O3-ZRO2 PRODUCED BY THE GAS-PHASE CONDENSATION TECHNIQUE

Nanophase (n-) ZrO2 was produced in its pure and partially stabilized form by the gas-phase condensation method. The material was examined by x-ray diffraction and Raman scattering to obtain information on the structural evolution of the material during sintering. Two types Of Y2O3-doped ZrO2 nanophase material were made: one by co-deposition of n-Y2O3 and n-ZrO2 in a consecutive manner and the second by mechanically mixing n-Y2O3 and n-ZrO2. We have determined that the co-deposition process is the most effective means of doping the n-ZrO2.
