Investigation of solid-phase interaction of Ln2O3 with CoO (Ln--Sm,Eu,Gd,Dy,Ho)
- 1. Ural'skij Gosudarstvennyj Univ., Sverdlovsk (USSR)
Description
A thermogravimetric analysis has been used to study the kinetics and mechan nism of solid-phase synthesis of cobaltites of the LnCoO3 composition (Ln=Sm, Eu, Gd, Dy, Ho) during the interaction of Ln2O3 powders with h CoO in the 920-1030 deg c range. The LnCoO3 synthesis is realized unde diffusion conditions. Kinetic parameters of the LnCoO3 production are clcu ulated. The rate of LnCoO3 solid-phase synthesis is shown to decrease with increasing re order number. The effect of gas atmosphere composition, pressure of mixture briquetting, velocity of air supply into the reactor on the rate and conditions of interactions is estimated
