Microwave sintering of tin oxide and zinc oxide mixtures – Formation of Zn2SnO4 spinel phase, densification and evolution of microstructure
Original language description
In this work SnO2-ZnO based ceramics were prepared and sintered using both microwave (MW) and conventional (CV) heating. Five different batches of samples were prepared – pure SnO2, ZnO and different weight ratios of these oxides (S80-Z20, S50-Z50, S20-Z80). Microwave sintering was conducted in a multimode cavity at 2.45 GHz in temperature range 900–1400 °C, with different heating rates 50–100 °C/min and dwell times 0–15 min. The changes of linear shrinkage, bulk density, open porosity and phase composition are discussed with respect to the heating rate, dwell time, sintering temperature and type of heating (MW vs. CV). During the MW heating results show changes of the dielectric loss with higher temperature in all prepared samples. MW sintering of composites significantly improved densification compared to CV sintering, due to favorable MW/material interactions. The formation of the Zn₂SnO₄ spinel phase was also observed, with its content varying depending on the initial composition.
