Glass-ceramics of the system Pb(Zr0.5Ti0.5)O3-GeO2

Abstract

Α thin film of glass-ceramics containing Pb(Zr0.5Ti0.5)O3 has been prepared by rapid quenching of a melt of the system Pb(Zr0.5Ti0.5)O3-GeO2 and subsequent heat treatment for crystallization. The dielectric constant of the glass-ceramics obtained by the heat treatment at 1000 °C for 2 h ranged from 96 to 123. An endothermic peak which is considered to show the ferroelectric-paraelectric transition was observed between 420 and 445 °C on the DTA curve of the glass-ceramics.
