Nonlinear electrical properties of zinc oxide ceramics with B2O3 additions

The effect of B2O3 additions on the I-V behavior of ZnO-based ceramics CZnO-Bi2O3-Co3O4-MnO2-NiO-TiO2) and its changes in response to an applied de current was studied. The introduction of B2O3 was shown to reduce shrinkage during sintering and raise the nonlinearity factor and the voltage drop across the sample at a Axed current density. The effect of B2O3 On the stability of I-V behavior depends on the temperature at which the electrical contacts were Formed.
