Experimental investigation of particle size distribution and morphology of alumina-yttria-ceria-zirconia powders obtained via sol-gel route

摘要

Background: Oxide-doped zirconia is currently commonly used ceramics in dental prosthetics. However, its use raises a lot of controversy. This is related to the stability of the zirconia metastable phases in the human mouth environment and it sensitivity for the so-called low-temperature degradation. A key way to avoid this type of negative phenomena is doping ZrO2 with selected metal oxides and choosing appropriate methods for the synthesis of ceramic powders.
