The stability of Y1Ba2Cu3O7-delta (YBCO) suspensions in various primary aliphatic alcohols (C1-C4) and in acetone has been studied by measurement of sedimentation density, electrophoretic mobility and specific conductivity. Maximum stability is observed for the suspension containing n-butanol as the dispersion medium. However, for the formation of a dense and adherent coating of YBCO on a silver substrate by electrophoretic deposition, the presence of an additive such as trichloroethylene is necessary. The best results are obtained when the trichloroethylene content of the medium is around 30 vol.%, for which the stability of the suspension is also found to be at its maximum. A mechanism for charge accumulation on the surface of YBCO particles in these suspensions has also been suggested.
