Abstract :

sToday we are familiar with a large series of �high temperature superconductors� based on the ceramic materials with layers of Copper-oxide spaced by layers containing Barium and other atoms. Most of these type super conductors containing yttrium compounds, it has a regular crystal structure while the Lanthanum version is classified as a solid solution. Here author calculated the particle size of the superconductor Lanthanum Zirconium Yttrium Barium Calcium Copper Oxide (La0.1ZrY0.9BaCa2Cu3O4.5+x) at different treating temperatures. It was prepared by the solid state reaction method via a high-energy ball milling process through mechanically assisted synthesis and calcined in a specially designed high temperature furnace. Here the authors characterized the sample by X-ray Diffraction (XRD), SEM and EDX. The structure of this material is found to be orthorhombic and is confirmed from the XRD results with JCPDS files and XPERT-PRO software, while a≠b≠c and α=β=γ=900. The particle size determination by the XRD analysis with Debye Scherrer�s formula, SEM, instrumental oadening and Williamson-Hall Plot method confirmed that the sample�s particle size is less than 100 nm.
