KINETICS OF SOLID-STATE REACTIONS IN DOPED BaTiO_3 POWDERED REACTANTS
掺杂 BaTiO_3粉料的固相反应及其动力学

Kinetics of solid-state reactions were studied by high-temperature X-raydiffraction with 40PbTiO_3+60BaTiO_3 and 20SrCO_3+80BaCO_3+100TiO_2 as examples.The temperature dependences of rate were obtained.The kinetic data were fitted to Catermodel for a diffussion-controlled,the kinetic parameters were calculated and the characterof reaciton and the relation between kinetic parameters was discussed.
