| Abstract Scope |
Tin oxide (SnO2) is a unique ceramic that does not densify under conventional (CV) and microwave (MW) sintering but exhibits significant changes in its effective properties. In this study, SnO2 ceramics were processed via CV, MW, and cold sintering (CS) to investigate their densification behavior and microstructural evolution. While CV and MW sintering did not achieve densification, MW sintering revealed interesting microwave/material interactions, influencing heating dynamics. In contrast, CS enabled densification at remarkably low temperatures without dopants, demonstrating its potential as an energy-efficient processing method. Additionally, the elastic properties of these ceramics were investigated, with changes correlated to microstructural evolution. These findings highlight the limitations of traditional sintering for SnO2, while unveiling new insights into MW sintering behavior and the effectiveness of CS. This study contributes to advancing sustainable ceramic processing and the development of functional SnO2 materials. |
