When synthesizing ceramic powders for use in high-temperature superconductors, the bulk fraction of the synthesized powder that is actually superconductive is often low. In the specific case of YBaCuO 1-2-3 synthesis, the oxygen content of the sintered material is delicate (often destroyed by moisture) and critical to the observation of superconductivity above 77K (N2 boiling point). An apparatus is proposed that will preferentially filter out superconductive particles from non-superconductive particles from a finely ground powder (~100 um). Filtered, superconductive material will then be sintered together (or drawn into a copper/brass carrying wire as is common with BSCCO) to yield a ceramic with higher bulk fraction superconductivity. This apparatus would allow inexpensive superconductors to be fabricated with loose tolerances/purities on starter chemicals and firing apparatus.
