Preparation of Zirconium Titanate Ceramics by Alloy Oxidation Method

Abstract:

In this paper, the investigations are presented for preparation of zirconium titanate ceramics by pressureless sintering of powders obtained by alloy oxidation method. Zr_xTi_1-xO₂ (x=0.40-0.60) powders were prepared by the oxidation of Zr-Ti alloys. The zirconium titanate powders were sintered in the temperature range from 1400 to 1600 °C for 3 h by pressureless sintering. The relationships among the composition, the relative densities and microstructure of bulk ceramic were studied by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results show the sintering and microstructure of single phase zirconium titanate ceramics varied with ZrO₂ content. The relative density of samples reaches the maximum value of near 92% when sintering temperature is up to 1600 °C. Irregular pores distributed uniformly among the particles in the sintered ceramics with homogeneous microstructure.
