Gel-casting of Fine Zirconia Using DMAA Gel System
Source abstract
Abstract
为了降低传统丙烯酰胺(AM)/ N,N-亚甲基双丙烯酰胺(MBAM)凝胶体系的毒性, 制备高固相量、低粘度的超细ZrO 2 ( D 50 =0.19um)浆料及高性能的生坯和陶瓷, 研究了低毒的N, N-二甲基丙烯酰胺(DMAA) /MBAM凝胶固化工艺及pH值和聚甲基丙烯酸铵(NH4PMAA)分散剂对浆料流变性的影响. 最终采用低粘度、高固相量、低毒性的浆料制备了性能优异的生坯和陶瓷. 浆料的固相量高达56vol%, 生坯表面光洁、不起皮、不开裂, 强度接近30MPa, 其内部颗粒结合紧密, 孔径呈单峰分布, ZrO 2 陶瓷的抗弯强度及断裂韧性分别为960MPa和17.3MPa . m 1/2 , 其结构均匀、致密性好、四方相ZrO 2 含量高.
