Abstract
Etching with fusion of NaOH delineates dislocations in the BaTiO3 crystals and by this use, the behavior of mechanically-treated crystal is investigated. When the crystal is subjected to a pointed impulse, a characteristic a-domain pattern appears near the point of contact. Annealing the mechanically-shocked crystal above 1000°C removes the pattern, while two parallel columns or parallel crosses of dislocation etch pits appear. It is supposed that the elastic strain may be released by taking place of a plastic flow upon heating. The part surrounded by parallel columns exhibits an anomalous birefringence, almost unchanged across the Curie point.Keywords
