Description
Summary:Titanates of gadolinium, europium, and dysprosium are considered potential candidate materials for use in the control rods of future nuclear reactors. GdEuTi.sub.2O.sub.7 and DyEuTi.sub.2O.sub.7 were synthesized by powder-pellet route and were characterized by using X-ray diffraction technique. Enthalpy increment measurements were carried out on these compounds in temperature range 795-1658 K by inverse drop calorimetric method by using a high-temperature differential calorimeter. Thermodynamic functions such as heat capacity, entropy, and Gibbs energy functions in the temperature range 298-1700 K were computed from the measured enthalpy increments.
