A study of nonstoichiometry and the electrical conductivity of erbium sesquioxide

The nonstoichiometric composition of Er 2 O 3 and the electrical conductivity of Er 2 O 3 were measured in the temperature range of 800–1050°C under oxygen partial pressure from 10 −5 to 2 × 10 −1 atm. The nonstoichiometric deviation, x in Er 2 O 3+ x was found to be
