摘要： 以无水乙醇作为分散介质,采用注浆成型工艺和真空烧结技术制备了光学质量良好的YAG透明陶瓷.双面抛光、厚度为3mm的YAG透明陶瓷样品(烧结温度1800℃)在可见光范围内的直线透过率为79%左右,在近红外波段的透过率为80%左右,接近理论透过率84%. 样品的平均晶粒尺寸约为30μm,晶界处和晶粒内部均无杂质和第二相存在, 也几乎没有气孔的残留.采用无水乙醇做分散剂进行注浆成型是一种很有发展潜力的透明陶瓷成型方法.

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.
