✦ Synopsis

Rubber ceramic composite, negative temperature coef®cient of conductivity (NTCC) thermistors, are widely used in industry because of the high dependence of their electrical conductivity on temperature. The effect of iron oxide (Fe 3 O 4 ) on the vulcanization process, DC conductivity, thermoelectric power, dielectric constant and I±V characteristics have been measured. Also the conduction mechanism is discussed. A hot-pressing technique has been used to enhance the microstructure core of rubber composites. It has been found that Fe 3 O 4 acts as a catalyst during vulcanization process and the characteristic time constant during vulcanization decreases as the content of Fe 3 O 4 increases.
