Abstract
Zinc stannate (Zn2SnO4) compound was prepared from the solid state reaction of ZnO and SnO2 powders. Samples of Zn2SnO4 for TEM investigation were prepared by applying a series of thinning and milling with argon ions (Ar+). The structural studies by transmission electron microscope TEM performed for the samples on a gold grid are explained. It is found that the lattice is of a face centered cubic (f.c.c.) type with lattice constant a = 8.68 Angstrom. The grain and pore sizes inside the bulk have been measured and compared with those obtained with the scanning electron microscope (SEM). They are then correlated to the sintering and pressing processes. No significant difference between the doped and undoped samples has been found.
