摘要：
Copper is an irreplaceable element in the synthesis of high temperature superconductors. In this paper, an investigation of the aqueous gelation of copper from two types of precursors, the cupric nitrate and the cupric acetate, is reported. The structure and properties of the gels obtained with various complexing agents and their transformations during heat treatment are compared. It is shown that a bloating property already reported in gels for superconductors, is maintained for gels with copper as the only metal, and is due to a layered structure. © 1990.
