Abstract
High-temperature superconductivity in ceramic oxides
is a new technology in which advances are occurring at a rapid pace. Here, the author describes some properties of a new nano crystalline ceramic
Type II superconductor, PbSrCaCuO. Type II
superconductors are usually made of metal alloys or complex oxide ceramics. The PSCCO perovskite phase structure was prepared by the conventional
solid state reaction technique. In
order to show the viability of the proposed method, super-conducting powder was
prepared in special furnace. The sample was analyzed by X-ray Diffraction
(XRD), Particle size determination, SEM and EDX. The comparison of XRD results
with JCPDS files confirmed the orthorhombic structure of the sample with a ≠ b ≠ c and α = β = γ = 90°. Scanning electron microscopy (SEM) studies revealed that its particle size
is in the nanometer range. It also confirmed the calculated value of particle size from Debye Scherrer’s formula. EDX spectrum shows the
elements of the sample. X-ray instrumental peak broadening analysis was used to
evaluate the size and lattice strain by the Williamson-Hall Plot method.
