Abstract

The NiO-Mn3O4 mixtures using cryochemically prepared powders have been made. Resitivity of the mixtures in the system with Ni1−x Mn2+x O4 has been measured as a function of temperature and composition. Bulk densities, temperature coefficient of resistance, activation energy, bias voltage and time constant have also been determined. A fairly wide range of composition exists in the system suitable for thermistor application.
