AN IMPROVED ROUTE TO THE SYNTHESIS OF SUPERCONDUCTING COPPER OXYFLUORIDES SR(2-X)A(X)CUO(2)F(2+DELTA) (A=CA, BA) USING TRANSITION-METAL DIFLUORIDES AS FLUORINATING REAGENTS
We report here a simple and efficient synthetic route to high temperature superconducting oxyfluorides. Solid phase fluorination of Sr2-xAxCuO3 (ACa, 0 ≤ x ≤ 2.0; ABa, 0 ≤ x ≤ 0.6) with the transition metal difluorides, CuF2, ZnF2, AgF2, NiF2, at relatively low temperatures (225-250°C) produces supe...
