The Effects of Thermal Evolution During Sintering Mechanism of Geopolymer-based Ceramics

Ceramics have gained extensive utilisation across diverse industrial domains owing to their exceptional mechanical, thermal, and chemical characteristics. Nevertheless, the conventional manufacturing process of ceramics frequently entails substantial energy expenditure and notable carbon emissions. Geopolymers, as a contrasting option, present an eco-friendly prospect by harnessing industrial by-products and employing alkali activation mechanisms to engender a robust binding agent. Geopolymer-based ceramics, stemming from these precursors, have exhibited great potential concerning sustainability and mechanical performance. This article presents a comprehensive review of the thermal effects during sintering mechanism of geopolymer-based ceramics. Besides, the study offers valuable insights into the intricacies of the sintering process and the ensuing microstructural evolution of geopolymer-based nepheline ceramics, thereby advancing the comprehension of geopolymer-based ceramics. The findings also provide guidance for the rational design and fabrication of sustainable ceramics materials, fostering enhancements in their mechanical properties.
