Abstract

BaTiO3 powder was prepared using the solid-state reaction method starting with BaCO3/TiO2 powder mixtures. After that, the resultant powder was treated in the temperature range (600 – 1400) K⁰ inside electric Oven. It is noticed that the heat capacity under pressure constant for input – and output components in reaction take values in the interval (10 – 37 ) kJ/ K⁰ in the above-mentioned range, while the free Gibbs energy changes decrease by value 0.47 kJ/mol in negative direction which indicates the stationary of reaction process but the changes of entropy have been taken values in the range
 (-0.0028 , -0.0055) kJ/mol.K⁰.
