Thermoanalytical investigation of YBa2Cu3O7−y superconductor: III. Preparation from mixed 2-ethylhexanoates of yttrium, barium and copper

Add time:08/25/2019    Source:sciencedirect.com

The preparation of YBa2Cu3O7−y from mixtures of the 2-ethyl-hexanoates of yttrium, barium and copper has been investigated by thermogravimetry (TG), TG-DTA (differential thermal analysis). X-ray diffractometry, and energy dispersion X-ray analysis (EDX). The mixture is first transformed to a mixture of BaCO3, Y2O3 and CuO below 500°C and then the perovskite formation proceeds. Kinetic analysis of TG data on the perovskite formation has been performed.
