Hydroxyl defect effect on the resistance degradation behavior in BaTiO3-based bulk ceramics

What is it about?

The IR degradation behavior of BaTiO3-based ceramics critically depends on the water vapor incorporation. We have used impedance spectroscopy (IS), transmission electron microscopy (TEM) and electron energy loss spectroscopy (EELS) to confirm transport of hydroxyl defects in ceramics.

Why is it important?

Our findings show that the incorporation of water vapor affects the reliability of BaTiO3-based ceramics significantly. Thus, we were able to clarify in details the reasons for the degradation behavior and point out the most importance factors related to the degradation behavior.
