摘要	The subsolidus phase relations in the SrO-Fe(2)O(3)-CuO, SrO-Fe(2)O(3)-Gd(2)O(3) and Gd(2)O(3)-Fe(2)O(3)-CuO systems have been investigated by the means of X-ray powder diffraction (XRD). All samples were synthesized in the air at 960 degreesC. There are nine binary compounds in the system SrO-Fe(2)O(3)-CuO. This system can be divided into twelve three-phase regions. A new ternary compound Sr(7)Fe(17)CuO(34) is identified. There are eight binary compounds and no ternary compound in the SrO-Fe(2)O(3)-Gd(2)O(3) system. Nine three-phase regions lie in this system. In the Gd(2)O(3)-Fe(2)9O(3)-CuO system, there are four binary compounds and no ternary compound. This system can be divided into five three-phase regions. The crystal structure of the binary compound SrGd(2)O(4) was determined by powder XRD, this compound belongs to an orthorhombic structure with space group Pnma. The lattice parameters are a = 10.1226(1) Angstrom, b = 3.4720(0) c = 12.0482(2) Angstrom. (C) 2002 Elsevier Science B.V. All rights reserved.
