摘要
本文研究了单相α Ａｌ２ Ｏ３ 及 Ｚｒ Ｏ２ （３ Ｙ） Ａｌ２ Ｏ３ 复相陶瓷的凝胶注模成型工艺， 着重研究了低粘度高固相体积分数浓悬浮体的制备及其固化在碱性条件下， 用自制的分散剂 Ｍ Ｎ 制备出固相含量高达６５ｖｏｌ％ 、粘度为２６７ｍ Ｐａ·ｓ 的α Ａｌ２ Ｏ３ 浓悬浮体， 以及低粘度下固相含量达５５ ｖｏｌ％ 的１０ ｖｏｌ％ Ｚｒ Ｏ２ （３ Ｙ） Ａｌ２ Ｏ３
The gelcasting of α alumina and binary zirconia alumina composites ceramic was further studied Special emphasis was placed on the preparation and gelation of concentrated suspension with low viscosity and high solide volume loading By using dispersant MN made in our laboratory, basic α alumina concentrated suspension whose solide loading as high as 65Vol% while viscosity as low as 267 mPa·s was prepared, besides,basic 10Vol% zirconia(3Y) alumina concentrated suspension with 55Vol% solide loading and low viscosity was prepared The properties of gelcasting body were also studied
