| Abstract: | 3Y-ZrO2 powder with a tetragonal phase content of 88%, particle size of 50～70nm and good dispersion has been prepared by using ZrOCl2.8H2O as zirconium source, Y2O3 as stabilizer, NH3·H2O as precipitation agent and PEG1000 as dispersant. The effects of heat treatment temperature on the synthesis results and particle size, the dosage of PEG1000 on the dispersion effect of powder have been studied by DTA-TG, XRD, TEM and so on. |
| Keywords: | 3Y-ZxO2 1000 precipitation method 3Y-ZrO2 powder polyethylene glycol(PEG)1000 |
