The amorphization of the Bi-Sr-Ca-Cu-O system by mechanical alloying starting from the individual oxides is examined. Several reactions concur to finally yield an amorphous matrix containing nanocrystalline copper oxide precipitates. Annealing the amorphous material leads, in a first step, to a crystalline solid solution, and, in a second step, to a low-Tc superconducting phase. Long term annealing allows the formation of the 85K superconducting phase.
