A freeze-drying approach to the preparation of HgBa2Ca2Cu3O8+x superconductor

Description
A freeze-dried mixture of metal nitrates was used to prepare the BaCaCuO precursor for the HgBa2Ca2Cu3O8+x (Hg-1223) superconducting phase. From this study we found that a highly homogeneous precursor is essential to increase the fraction of the Hg-1223 phase and to reduce the impurity phases. The quality of the samples prepared by using this method is highly improved in comparison with samples prepared by the conventional method of thermal decomposition of the nitrates. (author)
