摘要：

The electrical conductivity (sigma) and thermoelectric power (Q) of polycrystalline lithium-zinc ferrites sintered at 1200 and 1300-degrees-C was investigated as a function of temperature. The porosity and activation energy were calculated. It was found that the electrical conductivity is progressively increasing with increase of sintering temperature while the porosity and activation energy decrease continuously. The carrier concentration (n) and mobility (mu) of charge carriers has been discussed as a function of sintering temperature and temperature, respectively.
