Resumen

Organometallic-derived ceramic compositions surrounding YBa2Cu3O7–x (123) were evaluated via DTATG 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.
