分散剂浓度对真空热压烧结Y2O3透明陶瓷显微结构和光学性能的影响OA北大核心CSTPCD
Effect of Dispersant Content on Microstructure and Optical Properties of Yttrium Oxide Transparent Ceramics Prepared by Vacuum Hot-Pressing Sintering
以硝酸钇为原料,采用沉淀法成功制备出Y2O3纳米粉体,通过真空热压烧结工艺制备出Y2O3透明陶瓷.沉淀法是制备Y2O3粉体的常用方法,具有反应条件温和、粉体纯度高、成本低等优点,但由于粉体在沉淀过程中容易发生团聚现象,导致陶瓷的透明性降低.为了解决这一问题,在沉淀溶液中添加了 PEG4000作为分散剂,期望改善其粉体的分散性.同时,在真空热压烧结过程中,用钽箔包裹样品,有效地防止了碳污染的发生.本工作研究了 PEG添加量对Y2O3粉体和陶瓷的影响…查看全部>>
Introduction The quality of the powder is crucial for the performance of transparent yttria ceramics.The powder characteristics,such as size,shape,distribution,and agglomeration,directly affect the densification and microstructure of the ceramics.Co-precipitation is a common method for preparing yttria powder,which has the advantages of simplicity,low cost,and scalability.However,it also has some drawbacks,such as uneven particle size distribution,severe agg…查看全部>>
