对基于低毒性海因环氧树脂体系的氧化锆凝胶注模成型技术进行改进和发展,研究固相体积分数对浆料流变性能、凝胶过程、生坯和烧结坯力学性能的影响规律,并研究高性能氧化锆陶瓷盖板制备方法。研究结果表明:浆料黏度随固相体积分数增加而增大,但即使固相体积分数高达55.0%,浆料黏度也仅为0.606 Pa·s,能够满足浇注成型的要求;当固相体积分数为52.5%时,烧结坯强度的Weibull模量达到最大值13.38,即微观结构均匀性最佳,采用该固相体积分数的浆料成功地制备了表面光滑、厚度仅为0.4 mm氧化锆陶瓷盖板。

A low-toxicity gelling system based on hydantoin epoxy resin was developed for gelcasting of zirconia ceramic to fabricate the high-performance cover plate. The effects of the solid loadings on the rheological properties, gelation behaviors, mechanical properties of the green and sintered bodies were investigated. The results show that the viscosities of zirconia suspensions increase with the increase of the solid loadings. However, the suspension even with a high solid volume fraction of 55.0% still displays a moderate viscosity of 0.606 Pa∙s...
