Abstract
Nanosized (1 – x)ZrSiO4–xHf(OH)4 precursor powders are synthesized using the sol-gel method with the separate precipitation of components for obtaining (1 – x)ZrSiO4–xHfO2 ceramic composites. The thermal behavior of the precursor powders is studied using the differential scanning calorimetry and thermogravimetry (DSC/TG) method. By sintering powders precalcined at 850°C in air in the temperature range of 1000–1300°C, ceramic composites with high microhardness are obtained. The phase composition is determined by the XPA method.
