Effect of Nano-ZnO Particles on the Densification Properties and Conductivity of Nano-ZrO2(8Y)

Abstract

Abstract: With adding of nano-ZnO, nano ZrO₂(8Y) powder was used as raw materials for pressureless sintering at 1200℃. The results show that a small addition
of nano-ZnO accelerates the reaction between Y₂O₃ and ZrO₂ in ZrO₂(8Y). The ZrO_2(8Y)ceramic without nano-ZnO exhibits predominant tetragonal phase
with a small percentage of monoclinic, but the samples doped with nano-ZnO(0.5%～2.0% in mass)show a purely cubic phase. The densification and the conductivity of the
ceramic doped with nano-ZnO increase significantly.The densification of 94% and the conductivity of 9.02×10^-3cm^-1·Ω^-1 at 700℃ were
observed for the sintered body doped with 0.5wt% nano-ZnO.
