Abstract

SEQUINEL, T. et al. Sintering and second phase assignments in the SnO2-ZnO system. Cerâmica [online]. 2005, vol.51, n.319, pp.269-273. ISSN 0366-6913.  http://dx.doi.org/10.1590/S0366-69132005000300015.

Small ZnO additions in SnO2 systems result in ceramics with high densification. The aim of this work is to study the behavior of zinc addition ranging from 0.5 to 2 mol% SnO2 obtained by the Pechini method. The addition of 1.5 mol% ZnO assisted in the densification of the ceramic. However, further additions inhibited the process reducing the linear shrinkage by 14%. This behavior is justified by the formation of a second phase of zinc stannate in quantities close to 2 mol% as estimated by X-ray diffraction determining the lattice parameters of the SnO2-ZnO system.

Keywords : sintering; SnO2; X-ray diffraction.
