Thermal Stability of Sol-Gel Derived 6 Mole%CaO-ZrO₂ Ceramics

The thermal behavior of the hyperfine interaction at Zr sites on two sol-gel derived 6 mole% CaO-ZrO₂ powders, obtained from the particulate and non-particulate regimes, has been studied by Perturbed Angular Correlations and complementary techniques. The aim was to get experimental support on the th...
