Sinterability of Nd:YAG Powder Prepared by Alcohol-water Co-Precipitation Method
Pure-phase 2at% Nd:YAG powder was synthesized by alcohol-water co-precipitation method.2at% Nd:YAG ceramics were sintered at 1780 ℃ for 10 h under vacuum using the powder.Sintering ability of the powder was studied by comparing the results of alcohol-water solvent with those of distilled water solvent.The effects of different volume ratios of alcohol to water (R) on transparent ceramics have been also studied.Transparent ceramics having a transmittance of 40% in the visible wavelength have been sintered without sintering additive using the powder (R=0.8),which is much better than ceramics (16%) prepared using the powder derived from distilled water solvent under the same sintering conditions.In addition,the different R does not have much influence on the transmittance of ceramics in the present work.Compared with the results of distilled water solvent,the powders,using alcohol-water mixtures with different R as solvent,are more beneficial to the sintering of high transparent ceramics.
