Latest Patents
Jitendra P Singh holds a patent for a method of producing improved microstructure and properties for ceramic superconductors. The patent describes a process where a ceramic superconductor is produced by closely controlling the oxygen partial pressure during the sintering of the material. The resulting microstructure of YBa.sub.2 Cu.sub.3 O.sub.x shows enhanced sintering kinetics at reduced p(O.sub.2). The density of specimens sintered at 910°C increased from 79% to 94% theoretical when p(O.sub.2) was decreased from 0.1 to 0.0001 MPa. This increase in density is attributed to enhanced sintering kinetics, which arise from increased defect concentration and decreased activation energy of the rate-controlling species undergoing diffusion. Sintering at 910°C resulted in a fine-grain microstructure, with an average grain size of approximately 4 μm. Such a microstructure leads to reduced microcracking, strengths as high as 191 MPa, and high critical current density capacity.
