The high-temperature superconducting phase of the Bi-2223 system, with and without Pb, was prepared by the sol-gel method. The material was characterized by X-ray powder diffraction and by magnetization. An almost pure phase was obtained on the addit

Fluor-carbonate-apatites were prepared by a heterogeneous reaction from calcium carbonate, alkaline phosphate and fluoride and were doped with Zn2+ ions. The thermal stability of the doped apatites was studied by measuring the fluoride content before
