摘要

The newly-discovered homologous series HgBa2Can-1CunO2n+2+δ [Hg-12 (n-1)n] with n = 1, 2, 3,... possesses the highest superconducting transition-temperature (Tc) to date. Unfortunately, because of the complexity of its compound chemistry, it remains a challenge to prepare samples with pure or nearly-pure Hg-12 (n-1)n for both scientific and applied studies. In the present investigation, we report the successful development of a controlled vapor/solid reaction process for the synthesis of samples with up to 75 to 90% Hg-1212 and 65 to 75% Hg-1223 by volume, which display sharp superconducting transitions up to 135 K. Detailed steps of the process are presented and discussed.
