Electrical characterization of a non-sintered compound of the union Li2TiO3-CuO

The dynamic and bulk conductivity behavior of a nonsintered compound of the system Li2TiO3-CuO, ore analyzed as a function of temperature in the 200-8 50 degrees C interval. The compounds can be described [1] by Li2(1-x)/3Ti(1 -x)/3CuxO, they exhibit an exsolution reaction below 950 degreesC. a dynami c behavior of the group TiOy is considered the most probable source of elec tronic charge carriers. Frequency dependent conductivity follows a well def ined power law curve, sigma(omega) = sigma (o)+A omega (s). Temperature dep endence of conductivity relaxation time, A and s are sensitive to the exsol ution reaction occurring in the material. it is particularly interesting th at the parameter s, in an unusual manner, reflects the temperature at which the reaction is reached.
