Synthesis and Characterization of 3Y-TZP Powders by Stirring Ball Milling
3 mol% yttric(Y2O3)-stabilized tetragonal zirconia ( denoted as: 3Y-TZP) powders were synthesized by the reaction of Zr(CO3)2·nH2O,Y2(C2O4)3·nH2O,H2C2O4·2H2Oand H4C2O2-C2H5OH mixed via stirring ball milling. The curve of decomposition of precursors was studied according to differential thermal analysis and thermogravimetry (DTA-TG). The 3Y-TZP powders were confirmed by characterization of XRD, TEM and BET. These results shown that the size of the 3Y-TZP powders were in the range of about 18nm-28nm with good dispersion and the main phase of target production was tetragonal phase. When calcining temperature and holding time was higher, the size of particles grown up and the tetragonal phase volume fraction decrease gradually. And the calcining temperature has more significant effect.
