Thermal properties and homogenity range of Bi24 xCo2-xO39 ceramics

Original language description

Samples with different Bi2O3/Co2O3, ratio were prepared by ceramic route. Based on the results of DTA, XRD and SEM - EDX a section of phase diagram of the Bi-Co-O diagram in air atmosphere was calculated using the FactSage software. The sillenite structure of Bi24+xCo2-xO39 was confirmed and described. The Rietveld analysis confirmed SEM - EDX results. The heat capacity and enthalpy increments of Bi24Co2O39 were measured by differential scanning calorimetry (DSC) from 258 K to 355 K and by the drop calorimetry from 573 K to 973 K Above room temperature the temperature dependence of the molar heat capacity in the form C-pm = (1467.87 + 0.299410 . T - 15888378 . T-2) J K-1 mol(-1) was derived by least-squares method from the experimental data
