Latest Patents
Ponnusamy's latest patents focus on the fabrication of superconducting wires and rods that exhibit desired and consistent electrical and mechanical properties. His work specifically addresses materials based on Yttrium Barium Copper Oxide (YBCO) and Bismuth Strontium Calcium Copper Oxide (BSCCO). The initial step in his fabrication process involves creating an extrudable paste by mixing superconducting powder with various organic additives, including binders, plasticizers, lubricants, dispersants, and solvents. The process includes several critical steps: using a piston extruder to shape the wire or rod, drying to eliminate the solvent, and conducting a binder burn-out treatment to remove residual organic materials. Notably, YBCO wires require a sintering step, while BSCCO wires necessitate cold isostatic pressing and heat treatment. Ponnusamy's innovative approach also includes extruding hollow rods to prevent crack formation during drying and heating, ensuring the final product maintains its integrity and performance.
