Abstract: High-quality YAG transparentceramics were fabricated by vacuum sintering technique using the slip casting with anhydrous ethanol as the dispersion medium. The in-line transmittances of the polished sample with the thickness of 3 mm are about 79% in the visible band and 80% in the infra-red band, respectively, which are close to the the oretical transmittance of 84%. The average grain size of the sample sintered at 1800℃is about 30 μm. There are fewpores and no impurities or secondary phases at inner grains or grain boundaries.It can be expected that the anhydrous ethanol slip casting method is a very promising way for the transparent ceramic forming.
