Electrical conductivity of Cobalt Molybdate has been measured in the temperature range 100–600°C on pressed pellets of polycristalline sample. It has been found that CoMoO4-a is a p-type semiconductor while CoMoO4-b is a n-type semiconductor.

Different conduction mechanisms have been found depending on the temperature and the oxygen partial pressure. The nature of the major defects structures is discussed for both polymorphic forms of CoMoO4.
