Abstract

We report on the dispersion and gelling mechanisms of Al2O3 and Si3N4 suspensions fabricated via gelcasting. These systems were prepared by introducing bivalent ions into a gelcasting system known as ISOBAM, a water-soluble copolymer of isobutylene and maleic anhydride. The addition of metal ions negatively affects viscosity, while the influence of bivalent ions on the storage modulus is closely related to the microscopic configuration of ISOBAM. This configuration is altered due to the competition between particles and metal ions in the suspension to adsorb ISOBAM. An increase in the ionic potential of metal ions accelerates the gelling rate of Al2O3 suspensions and increases the surface area of ISOBAM self-assembly around the particles, thereby extending the microscopic conformation. In Si3N4 suspensions, the surface area of ISOBAM around the particles initially decreases and then increases, primarily due to pH changes resulting from the hydrolysis of metal ions and Si3N4.

二价离子对陶瓷悬浮液的分散和凝胶化的影响
我们报告了通过凝胶法制造的 Al2O3 和 Si3N4 悬浮液的分散和胶凝机制。这些体系是通过在异丁烯和马来酸酐的水溶性共聚物 ISOBAM 中引入二价离子而制备的。金属离子的加入会对粘度产生负面影响,而二价离子对储存模量的影响则与 ISOBAM 的微观结构密切相关。由于悬浮液中的颗粒和金属离子竞争吸附 ISOBAM,导致这种构型发生改变。金属离子离子电位的增加会加快 Al2O3 悬浮液的胶凝速度,并增加 ISOBAM 在颗粒周围自组装的表面积,从而扩展微观构型。在 Si3N4 悬浮液中,颗粒周围 ISOBAM 的表面积最初减小,然后增大,这主要是由于金属离子和 Si3N4 的水解导致 pH 值发生变化。
