摘要：

We have made investigations of the phase formation and microstructure on the ceramics obtained from a starting nanopowder mixture with the weight ratio ZnO: TiO2 = 4 : 1. Ceramic is obtained at different sintering temperatures, namely, 948, 1223 and 1473 K. Using the characterization methods of electron microscopy, energy dispersive microanalysis and X-ray diffraction phase analysis it has been shown that the ceramics structure is consisted of two dispersed phases of Zn2TiO4 and ZnO with the grain sizes being in range 0,5-1 mu m. It has been found also that, at ceramic's sintering temperature of 1223 K, the solid phase interactions are completed with the structure ZnO : Zn2TiO4 approximate to 1 : 1,5 phase ratio.
