The lattice parameters a and c, superconducting onset temperature T c and volume fraction rate of superconductive phase f s were studied for the Bi2Sr2CaCu208+y-6. Where 6 is the oxygen deficiency in that system per chemical formula unit. All of the above quantities rapidly decreased with increasing
