Sažetak
High-energy ball milling has been employed for mechanochemical treatment of TiO2 and ZrO2, thus facilitated the solid state reaction toward ZrTiO4. The ceramics with different degree of porosity were prepared by 8 h sintering of thus prepared nanopowder precursor at 1100, 1200, 1300 and 1400 °C. The solid state reaction was completed after sintering at 1200 °C. The correlation between the structure of ZrTiO4 ceramic (ZT) at the nano-scale and its electric response at different humidities was studied. Highly porous ZT ceramics sintered at 1100 and 1200 °C showed significant difference in electrical conductivity depending on atmosphere conditions indicating promising application as humidity sensors.
