ABSTRACT:
A method is provided for preparing a precursor of a superconductor containing atoms of oxygen, atoms of copper and atoms of at least two other metals and sufficient atoms of oxygen so that up to, but no more than, one atom of copper is in the trivalent state, in which method there are blended together, in finely divided particulate state, components containing atoms of the metals in the desired proportion with at least one of the components containing oxygen in an amount above that which would put more than one atom of copper into the trivalent state and thereafter milling the components together in a high energy system to a maximum particle size of about 5 microns for at least 99 weight percent of the blend.
