Abstract

The objective of this paper is to present an overview of the development of gel casting methods on synthesis techniques and the characteristics of gel casting porous ceramics and its applications. The gel casting method is a colloidal ceramic synthesis method that requires a short period for the ceramic body to develop. This review provides the latest developments in the gel casting process of synthesizing porous ceramics. At the beginning of the gel casting method development, the acrylamide (AM) system was the most commonly utilized system. Over time, the use of the AM system began to be minimized because of its toxicity. Researchers began to develop natural polymers as pore templates and natural minerals as raw materials in the gel casting method. In addition to polymers and raw materials, the gel casting process also requires additives such as gelling agents and dispersants. At the end of this review, a mapping of how to select the additives in the gel casting process, for AM systems and non-AM systems for the fabrication of porous ceramics is presented. The characteristic of porous ceramics produced by AM and non-AM systems are almost similar. Porous ceramic applications have been used as bone tissue supports, energy storage, filters, and catalyst support. This review will be a reference for future research related to the process of fabrication of advanced porous ceramics using the environmentally friendly gel casting method.

综述了凝胶浇铸法制备多孔陶瓷的研究进展

本文综述了凝胶浇铸多孔陶瓷的合成技术、凝胶浇铸多孔陶瓷的特点及其应用。凝胶浇铸法是一种胶体陶瓷合成方法，对陶瓷体的发育需要较短的时间。本文综述了凝胶浇注法制备多孔陶瓷的最新进展。在凝胶浇铸法发展之初，丙烯酰胺(AM)体系是最常用的体系。随着时间的推移，由于其毒性，AM系统的使用开始被最小化。研究人员开始开发以天然聚合物为孔模板，以天然矿物为原料的凝胶铸造方法。除了聚合物和原料外，凝胶铸造工艺还需要胶凝剂和分散剂等添加剂。在本综述的最后，介绍了如何在凝胶浇注过程中选择添加剂，用于制造多孔陶瓷的增材制造系统和非增材制造系统。增材制造和非增材制造的多孔陶瓷的特性几乎是相似的。多孔陶瓷应用已被用作骨组织支撑、能量储存、过滤器和催化剂支撑。本文的研究成果将为今后使用环保凝胶铸造法制备先进多孔陶瓷的相关研究提供参考。
