ABSTRACT

Y2O3 ceramic specimens were fabricated from the granular powder, obtained by spray drying process from theslurry. The slurry was prepared by mixing PVA binder, NaOH for Ph control, PEG and Y2O3 powder. The Y2O3 specimenwas shaped in size of Ø14 mm and then sintered at 1650oC. The characteristics, microstructure, densities and plasmaresistance of the Y2O3 specimens were investigated with the function of forming pressure and sintering time. Y2O3specimens were exposed under the CHF3/O2/Ar plasma, the dry etching treatment of specimens was carried out by thephysical reaction etching of Ar+ion beam and the chemical reaction etching of F− ion decomposed from CHF3. Withincreasing sintering time, Y2O3 specimens showed relatively high density and strong resistance in plasma etching test.
