“…SPS is a useful tool to control parameters like grain size and porosity which play a fundamental role in dielectric response. Therefore, SPS method has been widely used to sinter PZT and doped PZT ceramic oxides for electrical applications [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. However, volatilization of PbO at higher temperatures (>600°C) may disrupt the stoichiometry of synthesized PZT ceramic oxide [22,27,31].…”

In the present work, lead zirconate titanate PbZr 0.52 Ti 0.48 O 3 (PZT) bulk ceramic powders having composition aimed for morphotropic phase boundary (MPB) were synthesized by conventional solidstate reaction and sintered by novel spark plasma sintering (SPS) method. The samples sintered at four different temperatures of 800, 850, 900 and 950°C are found to have almost same density. The effect of SPS temperature on microstructure, phase constituents and dielectric properties is investigated. Rietveld refinement of XRD patterns of samples was carried out to estimate the phase composition revealing that the enhanced dielectric response is due to the presence of monoclinic phase along with the tetragonal phase in the synthesized material. The maximum room temperature dielectric constant ε r ∼950 was found for the sample sintered at 900°C. It is observed that the temperature has a significant role in resulting change of phase composition and dielectric performance of all the samples due to sublimation of PbO content.

In our previous work, we synthesized Pb(Zr0.52Ti0.48)O3 (PZT) ceramics by conventional and microwave sintering methods and studied their structural and electrical properties. We observed that the microwave sintered PZT ceramics show higher densification, fine and uniform grain size, higher dielectric constant, remnant polarization (Pr), and spontaneous polarization (Ps) in comparison to conventional sintered ones. In the present work, we studied the microstructure, phase formation, dielectric, ferroelectric and piezoelectric properties of the PZT ceramics synthesized by using Spark plasma Sintering (SPS) method. The SPS sintering temperature is lower (300 to 400 °C) than both conventional and microwave sintering methods. The dielectric constant at room temperature and at transition temperature shows higher values compared to the microwave and conventional sintering methods. This SPS sintering technique is currently attracting growing attention among productions engineers and materials researchers.

“…However, spark plasma sintering has only been used at the research level and has not been applied to industrial scale production. [246][247][248][249][250][251][252][253] C. High-T C lead-free systems High-temperature PTCR applications require isovalent A-site substitution of Ba 2þ with Pb 2þ , which is usually added as PbTiO 3 (T C ¼ 490 C), 254 and allows a Curie temperature increase beyond 130 C. For Ba 0.497 Pb 0.5 La 0.003 TiO 3 , the Curie temperature is around 360 C and results in a concomitant increase in the PTCR transition temperature. 255 This permits tailoring of the PTCR switching temperature to a particular high-temperature application.…”

Barium titanate materials displaying a positive temperature coefficient of resistivity are ubiquitously employed as thermistors in electrical current and voltage control systems, as well as in gas and thermal sensing applications. The positive temperature coefficient of resistivity effect is widely accepted to be a grain boundary-based phenomenon, although detailed studies on grain boundary structure and chemistry, and their influence on the resulting electrical properties, are seriously lacking. Tailoring of the positive temperature coefficient of resistivity electrical characteristics, for specific high-value applications, will require improved understanding and control over grain boundary phenomenon. A comprehensive overview of the development of barium titanate-based positive temperature coefficient of resistivity ceramics is initially presented. We then advance to a discussion on emerging grain boundary characterization techniques, specifically, a stereographic analysis of electron backscatter diffraction data that could assist in enhancing control over BaTiO 3 defect chemistry and microstructure, through characterization and subsequent manipulation of the population of grain boundary types. These techniques have great potential for increasing the understanding of the delicate interplay between processing conditions, chemistry, microstructure, and functional electrical properties, and are relevant to the development of advanced, high-performance ceramics and electroceramics in general. Contemporary advancements in the field, such as lead-free positive temperature coefficient of resistivity effect materials and multilayer miniaturized systems based on hypostoichiometric barium compositions, are reviewed. Finally, perspectives on future lines of thermistor research, with a focus on the energy sector, are presented including applications in gas separation and chemical sensing.
