Research on the Characteristics and Sintering Mechanisms of Y<sub>2</sub>O<sub>3</sub>-Ceramic

综述了氧化钇的光学、热力学性能及其应用，介绍了纳米陶瓷的烧结方法，其中详细介绍目前常用的氧化钇透明陶瓷的四种烧结方法：真空烧结、热压烧结、热等静压烧结和气氛压力烧结方法的烧结原理。另外，还介绍了氧化钇作为烧结助剂的另一重要作用。 This paper reviewed the optical, thermodynamics properties and application of yttrium oxide, summarized the success sintering methods of nanoceramics, introduced four ways about sintering yttrium oxide ceramics particularly, such as the principles of vacuum sintering (VS), hot pressing sintering (HP), hot isostatic pressing sintering (HIPS) and gas pressing sintering (GPS). In addition, it introduced another important role of Y2O3 which is sintering additive.
