I'm doing an experiment which requires the fabrication of a superconducting hollow cylinder but I am unable to find a firm which does custom manufacturing of this nature. I have found numerous which sell the high Tc powders (YBCO BSCCO). My question is if I do just buy the powders what could I do to form my cylinder? I was thinking I could either press it in to shape or add a binder of some sort. However I recognize the binder idea may diminish some properties of the HTS.

Any and all insight appreciated.
