Bulk superconductors of nominal compositions of tetragonal HgBa₂Ca _n-1Cu _nO _y (n=1–3) have been synthesized by a sealed quartz tube technique and high-pressure technique. In the present study nearly single-phase HgBa₂CuO _y was rather easily obtained by the former technique, but HgBa₂CaCu₂O _y and HgBa₂Ca₂Cu₃O _y phases were formed by high-pressure technique which presumably prevents decomposition of HgO.
