   There is a great military, space, and industry need for wireless systems that can operate under extreme conditions such as high temperatures and harsh chemical environments. Some of the applications inc lude planetary rovers for space exploration missions, wireless systems for mining and oil drilling applications, monitoring combustion turbines, and wireless environmental monitoring of first responders. Since antennas are the most critical components of a wireless system, design of antennas capable of surviving harsh environments is significant for overall system reliability and efficient communication. Yttria-Stabilized Zirconia (YSZ) is a ceramic, which has been recently used in a wide variety of gas sensing, biomedical, and thermal applications. YSZ has properties of high temperature tolerance, moisture resistance, high strength and corrosion resistance, and structural stability. One of the recent applications of YSZ is its utilization as a substrate material in the design of patch antennas. The electrical properties of YSZ allows for designing antennas with compact form factor and high efficiency due to high relative permittivity and low loss tangent.

2. Yttria-stabilized barium zirconate surface reactivity at elevated temperatures

   https://doi.org/10.1557/mrc.2020.43

   Abstract Material changes in yttrium-doped barium zirconate, BaZr 0.8 Y 0.2 O 3– x , were studied using in situ Raman spectroscopy and ex situ x-ray photoelectron spectroscopy analysis. During in situ Raman analysis, samples were heated to temperatures of 300–600 °C and exposed to both dry and humidified H 2 atmospheres. At the lower temperatures (300–450 °C), a new vibrational peak appears in the Raman spectra during exposure to humidified H 2 . The appearance of this feature is reversible, dependent on previous sample history, and possibly results from new, secondary phase formation or lattice distortion.
