✦ Synopsis
Superconducting Cuprates and Related Oxides. Part 10. In situ Neutron Powder Diffraction Investigation of the Solid State Synthesis of YBa 2 Cu 3 O 7-δ in a Flow of Oxygen at Temperatures up to 950 • C. -The in situ investigation of the solid state synthesis of tetragonal YBa 2 Cu 3 O 7-δ from a stoichiometric mixture of Y 2 O 3 , BaO, and CuO shows that two intermediate compounds are formed during the heating of the mixture, Ba 2 Cu 3 O 5+δ and BaCuO 2 , before the title compound is formed at 950 • C. Lower temperatures are not sufficiently high to ensure the pure tetragonal phase. -(CHRISTENSEN, A. N.;
