摘要：

The dielectric constants and dielectric loss tangents of Li-Ti ferrites of different composition were measured at room temperature using a capacitance bridge at low frequencies. It was observed that the lower concentration of titanium (< 0.6 mole of Ti) had minimal effect on the value of the dielectric constant, while for higher (> 0.6 mol of Ti) titanium dopants, the value of dielectric constant decreased very rapidly. For some compositions, the dielectric loss tangent curves exhibited a maximum at frequencies between 3 and 15 kHz. A qualitative explanation for the observed behaviour is given.
