Abstract:
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.
