AN INNOVATIVE TECHNIQUE TO PRODUCE HIGH JC, HIGH STRENGTH HTS WIRE USING NEWLY DISCOVERED PROCESSESS AND MATERIALS

THE COMPANY HAS DEVELOPED A CONCEPT TO PRODUCE FUNCTIONAL SUPERCONDUCTING WIRE USING THE HERETOFORE UNSUCCESSFUL "POWDER-IN-TUBE" PROCESS, DYNAMIC COMPACTION OF THE MELT-PROCESS PHASE OF SHS MATERIAL GENERATION, AND HIGH-PRESSURE OPERATION OF THE RESULTING ALIGNED CRYSTALLINE STRUCTURE. THE PRE-REACTION SHS POWDERS WILL BE PLACED IN A SILVER TUBE. THESE POWDERS WILL THEN BE IGNITED USING NORMAL SHS MIXTURES AND PROCESSES. AS THE FLAME PROGRESSES DOWN THE TUBE, CREATING A MELT-PHASE LIQUID, THE TUBE WILL BE SWAGED DOWN TO COMPACT THE MELT DYNAMICALLY. THIS WILL FORCE THE CRYSTALS TO LIE DOWN ALONG THEIR LONG AXES IN THE TUBE. UPON COOLING, THE SILVERTUBE WILL CONTRACT A GREATER AMOUNT THAN THE CERAMIC SUPERCONDUCTOR, PUTTING THE CERAMIC UNDER PRESSURE TO IMPROVE THE TC AND JC. THE COMPANY WILL USE ITS BISCCO-PB POWDER, WHICH HAS A TC ONSET OF 117K.
