The present paper systematically investigated the correlation of the starting powder characteristics and optical properties of neodymium doped transparent Y₂O₃(Nd:Y₂O₃) ceramics by hot pressing without a subsequent hot isostatic pressing (HIP) treatment. It was found that the in-line transmittance of Nd:Y₂O₃ was improved by using coarser primary particle size of Y₂O₃ and Nd₂O₃. Additionally, an increase in the hot pressing temperature from 1500 to 1600 °C was effective for improvement on optical qualities of Nd:Y₂O₃ ceramics without an exaggerated grain growth. These results demonstrate the possibility of fabricating highly transparent ceramics by a simple and cost-effective powder process and sintering technique.

本论文系统地研究了掺钕透明 Y ₂ O ₃ (Nd:Y ₂ O ₃ ) 陶瓷的起始粉末特性与光学性能之间的相关性，该陶瓷通过热压而无需后续的热等静压 (HIP) 处理。发现通过使用更粗的Y ₂ O ₃和Nd ₂ O _{3 的}初级粒径，Nd:Y ₂ O ₃的在线透射率得到改善。此外，将热压温度从 1500 °C 提高到 1600 °C 可有效改善 Nd:Y ₂ O _{3 的}光学质量陶瓷没有夸大的晶粒生长。这些结果证明了通过简单且具有成本效益的粉末工艺和烧结技术制造高透明陶瓷的可能性。
