Mason(1) and Caspari and Merz(2) have made measurements of the electromechanical properties of barium titanate. Working with polycrystalline ceramics Mason(1) observed only a second order electro-strictive effect, since the first order piezoelectric effect was annulled because of the random orientation of crystal axes. Caspari and Merz(2) made static and dynamic electromechanical measurements on single...
The non-linearity of the dielectric behavior of Barium Titanate single crystals above the 120°C transition has been investigated in the temperature range 120°C to 150°C. The single crystals used in this experiment were grown in our laboratory. They are characterized by a very high peak of the dielectric constant at the Curie point (16,000).
