Title: Roy J Rayne: Innovator in Superconducting Materials
Introduction
Roy J Rayne is a notable inventor based in New Carrollton, MD (US). He has made significant contributions to the field of superconducting materials, holding a total of 2 patents. His work focuses on processes that enhance the production and properties of high-temperature superconductors.
Latest Patents
Rayne's latest patents include a process for making superconducting PBSCCO and PBSCCO parts. This innovative process allows for the production of the 2223 phase of (Pb,Bi)SrCaCuO much faster than existing methods. The steps involve calcining a precursor powder mixture while ensuring intimate mixing through intermediate grindings. The calcination product is then compressed into a consolidated body and heated to form essentially phase pure 2223 (Pb,Bi)SrCaCuO. Additionally, he developed a fast process for creating a (Pb,Bi)SrCaCuO part with a high critical current density (J.sub.c). This involves pressing calcined and reacted (Pb,Bi)SrCaCuO powder into a green body and sintering it for a selected time to establish superconducting electrical contact between grains without causing void formation or distortion.
Another significant patent is for a machinable oxide ceramic. This high Tc ceramic superconductor is created by mixing stoichiometric amounts of Bi.sub.2 O.sub.3, SrCO.sub.3, CaCO.sub.3, and CuO, followed by removing carbonates, melting the mixture, and casting it into a mold. This process induces superconductivity and promotes the growth of randomly oriented platelets in the cast.
