“…TiC formed the smallest carbide nanostructures with an average particle size of 24 ± 8 nm and was found to be incorporated within an amorphous carbon matrix (Figure 2A). The high-resolution (HR) TEM (Figure 2B) analysis showed the presence of a crystalline TiC core 55 surrounded by an amorphous material, which can be either from the carbon matrix or particle surface oxide and oxycarbide. ZrC samples were composed of carbide particles with an average size of 31 ± 9 nm, along with a few larger (>150 nm) amorphous carbon particles (Figure 2D).…”

Refractory nanostructures can be low-cost and chemically and thermally robust alternatives to metal-based plasmonic materials. While transition metal nitrides have received much attention recently, there has been less emphasis on their closely related non-layered carbide counterparts. In this work, plasmonic group IV transition metal carbide (TiC, ZrC, and HfC) nanostructures were prepared using a facile magnesiothermic reduction method, which yielded a phase pure product. TiC, ZrC, and HfC with rock salt crystal structures and an average particle size of 24, 31, and 42 nm, respectively, were obtained by reacting corresponding metal oxide, magnesium, and biochar in the solid state. Calculations performed using a finite element method predicted these group IV carbide nanostructures to have localized surface plasmon resonance in the UV region between 150 and 175 nm. The photothermal transduction efficiency of each carbide was explored to further verify the plasmonic behavior. HfC was found to have the highest photothermal transduction efficiency of 73%, followed by ZrC (69%), and then TiC (60%) at 365 nm.

“…High heating rates enable the flow of direct current through the sintered material, which prevents grain growth and positively affects the density of the material [13]. At high local temperatures, spark plasma is generated momentarily for optimal thermal and electrolytic diffusion, and a low-voltage current pulse increases the Materials 2023, 16, 5756 2 of 14 kinetics of diffusion processes [14]. Such conditions favor grain-boundary and surface diffusion; as a result, densification dominates over grain growth [15].…”

In this paper, spark plasma sintering was used to obtain and investigate (Pb0.97Ba0.03)(Zr0.98Ti0.02)1−xSnxO3 (PBZTS) ceramic materials for x = 0, 0.02, 0.04, 0.06, and 0.08. Crystal structure, microstructure, dielectric and ferroelectric properties, and electrical conductivity tests of a series of samples were carried out. The SPS sintering method ensures favorable dielectric and ferroelectric properties of PBZTS ceramic materials. X-ray studies have shown that the material has a perovskite structure. The samples have a densely packed material structure with properly crystallized grains. The fine-grained microstructure of the PZBZTS material with high grain homogeneity allows the application of higher electric fields. Ceramic samples obtained by the SPS method have higher density values than samples obtained by the classical method (FS). The permittivity at room temperature is in the range of 245–282, while at the phase transition temperature is in the range of 10,259–12,221. At room temperature, dielectric loss factor values range from 0.006 to 0.036. The hysteresis loops of PBZTS ceramics have a shape typical for ferroelectric hard materials, and the remnant polarization values range from 0.32 to 0.39 µC/cm2. The activation energy Ea values of the PBZTS samples result mainly from the presence of oxygen vacancies. The PZT material doped with Ba and Sn and sintered via the SPS method has favorable physical parameters for applications in modern devices such as actuators or pulse capacitors.
