Abstract

The influence of Ba2Ca2Cu3Ox precursor on the synthesis and properties of (Hg,Pb)Ba2Ca2Cu3O8+delta has been examined. Fine homogeneous Hg-free precursor powder of Ba2Ca2Cu3Ox of desirable phase composition was prepared by sol-gel method using EDTA acid as a complexing agent. A reproducible superconducting sample of Hg0.8Pb0.2Ba2Ca2Cu3O8+delta with fine-grained, dense microstructure, composed predominantly of (Hg,Pb)-1223 phase and with advantageous magnetic properties, was synthesized by high pressure crystallization in mercury environment of well-calcined Ba2Ca2Cu3Ox precursor.
