Different methods of deviating efficiency exist for preparation of Hg-Ba-Ca-Cu-O high-T-c superconductors. They may be divided into such fundamental groups, which lead to different kinds of Hg-based compounds having unlike macroscopic and microscopic characteristic features. This paper analyses the relationship between some efficient preparation procedures and superconducting properties of different compounds resulting from them. Not only are the effects of practical methods, which produce high-quality single-phase or nearly single-phase materials of the homologous series Hg1Ba2Can-1CunO2n+2+delta investigated but the deviations from them and their influence on the developing characteristics of samples are also evaluated.
