Abnormal Expansion Along the Synthesis of Zinc Stannate: A Way for Porous Ceramics Without Addition of Pore Generators

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
The abnormal expansion associated with the simultaneous synthesis and sintering of Zn2SnO4 from ZnO and SnO2 is due to the reaction mechanism and correlated with the conversion. This phenomenon opens the way to manufacture porous ceramics without the addition of pore generators, simplifying the process, and especially the thermal treatment.
