TL;DR: In this article, the effects of ZrO2 interphase on the mechanical and dielectric properties of SiCf/SiC composites were studied, and the results showed that the flexural strength of the composites with and without the interphase are 261 and 103 MPa, respectively.
Abstract: Zirconia (ZrO2) coatings were successfully prepared on KD-II SiC fibers by sol–gel approach in zirconyl chloride and ethanol–water solution. Subsequent heat treatment at 1000 °C was done in vacuum. Phase composition and morphological characteristics of the ZrO2 coatings were investigated by XRD, FTIR, and SEM. The SiCf/SiC composites with ZrO2 coatings as interphase were fabricated by chemical vapor infiltration (CVI). The effects of ZrO2 interphase on the mechanical and dielectric properties of composites were studied. The results show that the flexural strength of SiCf/SiC composites with and without ZrO2 interphase are 261 and 103 MPa, respectively. It is demonstrated that ZrO2 interphase can effectively adjust the interfacial bonding strength and improve the mechanical properties of SiCf/SiC composites. In addition, both the real and imaginary parts of the complex permittivity (ϵ′ and ϵ″) of the SiCf/SiC composites with ZrO2 interphase are higher than those of without ZrO2 interphase. The effective absorbing bandwidth (below −10 dB) of SiCf/SiC composites with ZrO2 interphase is 1.6 GHz and the lowest reflection loss is −11.5 dB when the sample thickness is 2.7 mm.

TL;DR: In this paper, the specific and molar electric conductivities of propylene carbonate solutions of Et4NBF4 with concentrations of 0.15-1.4 m were determined at 283.15, 298.15 and 313.15 K. The concentration dependence of electric conductivity was described in terms of the Castell-Amis equation.
Abstract: The specific and molar electric conductivities of propylene carbonate solutions of Et4NBF4 with concentrations of 0.15–1.4 m were determined at 283.15, 298.15, and 313.15 K. The temperature dependence of the electric conductivity of the system was analyzed. The concentration dependence of electric conductivity was described in terms of the Castell-Amis equation. A comparative analysis of the charge transfer in Et4NBF4 and LiAsF6 systems in propylene carbonate was performed using the concept of quasicrystallinity of concentrated electrolyte solutions. The range of potentials in which the electrolyte solutions are stable on a platinum electrode was determined.
