英文摘要：

Transparent Y2O3 ceramics are a sort of highly valuable functional materials for the outstandingly optical and thermal properties. Nowadays, it has become the replacing material of single crystal. According to some foreign and domestic research fruits, the research progress of transparent Y2O3 ceramics is briefly introduced, including powder synthesis, compaction, sintering and machining. Fabrication processes of transparent Y2O3 ceramics are elaborately described. The reasons for cracking in powder compact are expatiated on.
