“…It can be observed that there are three stages of mass loss before the mass of the material becomes constant from 600 up to 1000 • C where 1000 • C is the maximum operating temperature of the instrument. The mass loss from room temperature to 600 • C corresponds to the evaporation of water and decomposition of thermally unstable organic matter [38][39][40]. This result suggests that the precursor should be heated at a minimum temperature of 600 • C for a certain length of time in order to obtain the desired product.…”

“…However, this method is time-consuming and energy intensive. Many other routes for the preparation of BaTiO 3 powders such as the sol-gel [13,14], hydrothermal [8,15,16], precipitation [17,18] and combustion methods [19] have been reported. In addition, novel methods that have been reported for fast sintering, such as spark plasma sintering (SPS) [20] and microwave sintering [21], are unique alternatives to conventional sintering.…”

BaTiO3 nanopowder was synthesized at low temperature by using an alkoxide-hydroxide sol-gel method and were sintered by microwave processing. Microwave sintering of BaTiO3 was carried out at different temperatures for 20 min to get dense ceramics. The phases, morphologies, crystal structures and weight losses of the synthesized and sintered materials were characterized by using Xray diffraction (XRD), Field-emission scanning electron microscope (FE-SEM), Raman spectroscopy and Thermo-gravimetric analyzer (TGA). The materials could only be sintered densely at lower temperatures (1050 − 1150 • C). Enhancements of the dielectric constant (εr ∼ 3500 at 100 kHz) and the remnant polarization (Pr ∼ 6.90 μc/cm 2 ) were found for BaTiO3 microwave-sintered at 1150 • C, which values were higher than those obtained by the conventional sintering. P-E loops confirmed the better ferroelectric nature of the microwave-sintered BaTiO3.

“…Currently, in situ VT-XRD has been extensively employed to study the formation or characterization of PbTiO 3 [37], BaTiO 3 [37], calcium phosphate [38], hydroxyapatite (HA) [39,40], sodium yttrium fluoride [41], g-Bi 2 MoO 6 [42], CoAl 2 O 4 [42], silicon nitride compounds [43], and others. This technique offers an opportunity to follow thermodynamic phase changes at elevated temperatures.…”
