Study of PbTiO3-Based Glass Ceramics Containing SiO2

Abstract EN

Glass samples with composition 50PbO : 25TiO2 : (25-X) B2O3 : XSiO2 (with X = 0, 1.5, 2.5, 3.5, and 5 mol%) were prepared by conventional quenching technique.

These glass samples were converted to glass ceramics by the two-stage heat treatment schedule.

Formation of ferroelectric lead titanate phase in the glass ceramics was confirmed from the XRD.

The density, CTE, and dielectric constant of the glass and glass-ceramic samples were measured.

The glass-ceramic sample containing 2.5 mol% SiO2 exhibited the highest dielectric constant.

The SEMs of glass-ceramic samples were studied.

The P-E hysteresis loop studies also revealed the highest remnant polarization for this sample, which has a potential for being developed for practical applications.
