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.

International Journal of Ceramic Engineering &Science, Volume 8, Issue 1, January 2026.ABSTRACT When the surge arrester is subjected to the working voltage for an extended period, it undergoes alternating current (AC) aging, which degrades the arrester's parameters and affects the safety of the power grid. Ni2O3 is an important additive in the ZnO varistor formulation, and its doping ratio significantly influences the performance of the ...
