摘要：
Cooling a melt of a Bi-Sr-Ca-Cu-O system (Bi:Sr:Ca:Cu=4:3:3:4 or 2:2:2:4) from 1000degreesC-1050degreesC yielded crystals of a new red-colored nonsuperconducting phase, accompanying the superconducting 2212 and 2201 phases. Based on the EPR spectra, it was concluded that copper is univalent in this compound. The new phase has a composition Bi2.2Sr1.6Ca1.3Cu2Ox. The X-ray diffraction pattern has been indexed, and the unit cell parameters of the phase have been determined: space group P2/m, a = 12.93, b = 4.55, c = 10.94 Angstrom; beta = 102.72degrees.
