ABSTRACT: X-ray crystallography
is concerned with discovering and describing the crystal structure. 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, PbBaTiO. Type II superconductors are usually made
of metal alloys or complex oxide ceramics. The PBT perovskite phase structure was
prepared by the conventional solid state reaction technique. 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 tetragonal structure of the sample
with a = b ≠ c and α = β = γ = 90°. Scanning electron microscopy (SEM)
studies revealed that its particle size was 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.
