摘要/Abstract

摘要： 分散良好的高固含量悬浮液是胶态成型方法获得微观结构均匀且尺寸精确的陶瓷素坯的前提,也是制备高光学质量透明陶瓷以满足光学窗口用需求的基础。本文旨在通过柠檬酸三铵(TAC)和聚丙烯酸铵(A40)两种分散剂的协同作用来提高Y₂O₃悬浮液的分散稳定性。研究了双分散剂混合比例对Y₂O₃悬浮液稳定性及成型素坯微观结构的影响,确定了双分散剂体系在提高Y₂O₃悬浮液固含量和稳定性方面的优势。结果表明,在TAC和A40的质量比为 7∶3条件下所制备的Y₂O₃悬浮液固含量可达38%(体积分数),成型的素坯微观结构均匀且颗粒致密堆积,素坯经1 800 ℃真空烧结后得到了直径为9 mm、厚度为1 mm的Y₂O₃透明陶瓷,在800 nm处透过率为70.34%。

Abstract: The preparation of a well-dispersed, high solids content suspension is the foundation for colloidal forming methods to achieve ceramic green bodies with a uniformly microstructure, and meet the application requirements of various optical window materials. This article aims to enhance the dispersion stability of Y₂O₃ suspension by utilizing the synergistic effect of two dispersants, namely triammonium citrate (TAC) and ammonium polyacrylate (A40). The influence of the mixing ratio of two dispersants on the stability of Y₂O₃ suspension and the microstructure of formed green bodies were mainly investigated, and the advantages of the dual dispersant system in improving the solid content and stability of Y₂O₃ suspension were determined. The results show that the solid content of Y₂O₃ suspension could reach 38% (volume fraction) under the condition of TAC to A40 mass ratio of 7∶3. A uniformly microstructure and densely packed particle was achieved. Y₂O₃ transparent ceramics with a diameter of 9 mm and a thickness of 1 mm were obtained by vacuum sintering at 1 800 ℃, with a transmittance of 70.34% at 800 nm.
