Abstract

Organometallic-derived ceramic compositions surrounding YBa2Cu3O7–x (123) were evaluated via DTA-TG runs and dilatometric densification. The compositions were either Y, Ba or Cu deficient respect to 123. For the Yttrium deficient compact the presence of liquids containing 0–1.3 mole %YO1.5—capable of dissolving the 123 grains—can promote a rapid sintering behavior. For Copper deficient compact the main densification/contraction mechanisms were delayed till 985 °C. For both Barium and Copper deficient compacts a strong exudation of liquids was detected at 990 °C and 1020 °C, respectively.
