Modulation techniques for measuring specific heat, thermal expansivity, temperature
derivative of resistance, thermopower, and spectral absorptance are reviewed. Owing to the …

The modifications of structural and functional properties induced by the gradual increase of
porosity from 4 vol% to 26 vol% produced by addition of polymeric sacrificial templates in …

This chapter considers basic modulation measurements, including calorimetry under high
pressures. For our purpose, it is convenient to divide the whole temperature range of …

Ferroelectric barium titanate ceramics with grain sizes in the range (0.5, 20) µm were used
for a comparative study of grain-size influence on the ferro-para phase transition and its …

Abstract Single-phase Ba 1-x Sr x TiO 3 (BST) perovskite ceramics with 0.3≤ x≤ 0.4 were
prepared from powders synthesized via sol-gel route. The compositions have the …

Grain size dependent functional properties and mainly ferroelectric and dielectric
characteristics of electroceramics remain a hot topic related both to basic science and …

Ageing properties of weak field dielectric constant and losses of (Hf, Zr)-doped BaTiO 3
ceramics in various crystalline phases are studied, and compared with those of pure …

Barium titanate ceramics having grain sizes between 0.5 μm and 20μm were used in a
comparative investigation of the ferro-para phase transition, by recording the temperature …

We have succeeded to synthesize nanopowders of BaTiO 3 with the freeze-drying method,
using barium acetate Ba (CH 3 CO 2) 2 and titanium isopropoxide Ti (Opr i) 4 precursors …

Dielectric barium titanate-based perovskite (BaTiO3) has emerged as one of the most
popular multilayer ceramic materials for its versatile properties. However, the intrinsic …
