Abstract
DTA analysis of YBa2-xSrxCu3Oy showed that the temperature of the peri tectic peak increases with Sr-content. Thermogravimetric measurements showed that the oxygen non-stoichiometric range between 900 degrees C and room temperature decreases as the Sr-content increases. From these results, it is proposed that the Sr stabilizes the 1:2:3 phase, given rise to a doped structure with a larger cohesive energy.
