Calcium titanate does not exhibit piezoelectric behaviour. However, in present study
such behaviour is observed in calcium titanate prepared by sol-gel synthesis and densified
by field assisted sintering. Presumably, the instability of regular TiO6 octahedra
results in the off-centering of titanium positions in nanostructured bulk calcium
titanate. As a consequence, piezoelectric behavior is observed in calcium titanate
which is referred to "pseudo-piezoelectricity". This particular response is of great
interest in biomedicine because it can improve osseointegration of implant materials.

Die vorliegende Arbeit weist piezoelektrisches Verhalten von Calciumtitanat nach,
das mittels Sol-Gel Synthese hergestellt und mittels Feld-Aktiviertem Sintern verdichtet
wurde. Vermutlich verursacht die Instabilität regulärer TiO6 Oktaeder eine Verschiebung
der Positionen von Titanatomen in Festkörpern aus nanostrukturiertem Calciumtitanat.
Daher kann piezoelektrisches Verhalten, genannt "Pseudopiezoelektrizität", in Calciumtitanat
beobachtet werden. Dieses Ergebnis ist von großem Interesse für biomedizinische Anwendungen
zur Verbesserung der Osseointegration von Implantatmaterialien.
