摘　　要：介绍了ZrO2陶瓷的注凝成型工艺原理,浆料分散机理和素坯干燥理论,对低毒、无毒凝胶体系开发及ZrO2超细粉注凝成型的研究进展进行了综述,重点分析了pH值、分散剂、粉体特性及固相含量对ZrO2注凝成型浆料流变性能的影响,对ZrO2陶瓷的注凝成型工艺发展趋势进行了展望。The principle of gel-casting process, the dispersion mechanism of slurry and the drying theory of green compacts for zirconia ceramic are introduced. Research progress on low-toxic/nontoxic gel forming system and gel-casting of zirconia ullrafine powder is introduced, in which the effects ofpH value, dispersant, powder characteristic, solid loading on the rheology behavior ofsuspensoid are analyzed detailedly. At last, the trend of development in gel-casting ofzirconia ceramic is forcasted.
