Preparation of the silver nanoparticles and their deposition into the pore system of the Bi(Pb)-Sr-Ca-Cu-O superconductor
Original language description
Cuprate superconductors are a subject of studies for a long time. Superconducting properties can be improved by changing the phase composition, by the variation of the quality of grain boundaries but also and mainly by changing the macroscopic and microscopic ordering of the grains, their size and orientation. Another way of improvement is addition of microscopic particles to the material as possible pinning centres. This is usually practiced by addition of these particles into base material before itsmanufacturing. The object of this work was to make an addition of the silver nanoparticles into the superconductor's porosity system in order to gain standard procedure applicable to make an addition of any other particles into this porous material afterits preparation. The samples were prepared by standard solid state reaction with Bi2O3, PbO, SrCO3, CaCO3 and CuO as starting compounds. Mixed powder was twice calcined at 800 °C for 24 hours and then pulverized. Final powder was pressed
