We reported on the effects of water or organic solvents on the superconductor in the Bi-Pb-Sr-Ca-Cu-O system in the previous reports. In this study, We are concerned with their effects on the preparation processes such as mixing and milling in the solid-phase reaction method. The organic solvents used in the experiment were ethylalcohol, methylalcohol, acetone and toluene. Wet-mixing and wet-pulverizing with water or some organic solvents influenced the superconductor to some extent. Typically, wet-mixing with toluene made the Tc(end) lower by 3 K than the mixing without toluene. Wet-pulverizing with water after semi-sintering resulted in higher Tc.
