摘要：
This invention provides a process for the preparation of the precursor used in the fabrication of Y--Ba--Cu--O superconductors. This process mainly uses solgel technology via the nitrate route by using a dicarboxylic acid. Among the dicarboxylic acids, oxalic acid is the best for preparing the precursor which can be fabricated into a good superconductor.
