Název v původním jazyce

Influence of the size and distribution of the pores on the properties of the high temperature superconductors Bi(Pb)-Sr-Ca-Cu-O

Popis výsledku v původním jazyce

In this work the influence of the porosity of the bulk high temperature superconductors Bi(Pb)-Sr-Ca-Cu-O on the superconducting properties was investigated. The samples were prepared using the standard solid state reaction. More porous material was prepared by the addition of the noncalcined material into the samples since sintering. Less porous sample was prepared by repeated sintering of the sample. It has been discovered that samples with bigger pores have lower critical current densities then samples with area of pores shifted at lower diameters of the pores. Critical temperatures of all samples were practically the same. Also the phase composition of the samples determined by XRD shows no fundamental differences. This research could be useful instandard practise of these materials and in the future research of the special composition materials.
