On the search for a stable BiPbSrCaCuO 2223 polytype

Technical Report:

Abstract

A new crystallographic form of the 2223 polymorph has been identified by means of convergent beam electron diffraction, with a c-axis of 36.8 Aangstroems and with the space group F2dd. In contrast to the well known 2223 polymorph of the compound Pb-Bi-Sr-Ca-Cu-O with a c-axis of 37.1 Aangstroems and a space group of A2aa/Amaa, which has a limited shelf life, the new form is stable at room temperature and in normal atmospheric conditions, and appears to retain the high Tc characteristics of the A2aa/Amaa form. 12 refs., 4 figs.
