DEPENDENCE OF THE ELECTRIC-FIELD ON THE SPECIFIC SURFACE CONDUCTIVITYOF PBO2, 3PBO.PBSO4 AND 4PBO.PBSO4

Our investigation is based on the relationship between the electric fi eld and the surface conductivity of PbO2, 3PbO . PbSO4 and 4PbO . PbSO 4, and is evaluated at different temperatures and duration times. We u sed a suspension of each sample in a weak solution of H2SO4 (2.5 X 10( -6) M) which has been titrated with a stronger acid solution of H2SO4 (1.58 X 10(-3) M). The conductivity was measured during agitation, (K) over bar and during sedimentation, K. When (K) over bar/K = 1, the is o-conductivity point under these specific conditions was analysed. The electrical field influenced the displacement of the particles in the solution.
