Erratum to: Ferroelectric properties of a material made of titanium oxide

An Erratum to this article was published on 01 November 1959

Summary

A ceramic-type material was prepared from TiO2 by a special technique described elsewhere (1). Although this material is very similar to rutile, ist properties are quite different. Suitable specimens were prepared with a view to prove the existence of ferroelectric properties, and readings were taken, as shown in the accompanying graphs: 1) The variations of the capacity against bias voltage; 2) the hysteresis loops with varying temperatures and voltages; 3) variations in the dielectric constant in a wide range of temperatures, from − 60 °C to + 350 °C. These results prove the existence of a ferroelectric phenomenon. It is supposed that it should be possible to use this material as a test material for further research onmatter in the solid state.

Riassunto

Con speciale tecnica descritta altrove (1) è stato preparato un materiale quasi ceramico costituito di TiO2. Questo materiale che apparentemente è rutilo ha proprietà tutto affatto differenti. Campioni adatti sono stati preparati allo scopo di provare l’esistenza di proprietà ferroelettriche. Sono stati perciò eseguiti, come dimostrano i grafici riportati, misure riguardanti: 1) le variazioni di capacità al variare della tensione impressa; 2) i cicli di isteresi al variare della temperatura e della tensione; 3) la costante dielettrica al variare della temperatura in un vasto campo di temperature cioè da − 60 °C a + 350°C. Tali misure danno la prova dell’esistenza di un fenomeno ferroelettrico.
