Chemical and biological agents continue to pose a threat to U.S. national security. The development of next generation of devices to sense, detect, filter, and remove these threats remains a priority of the U.S. Department of Defense. Zr(OH)4 is currently being developed as a decontaminant and is being engineered into suitable forms capable of removing chemical warfare agents. As such, having a detailed understanding of the local structure of amorphous Zr(OH)4 and heat treated ZrO2 analogs is a crucial step in developing these compounds as  suitable countermeasures against chemical threats. In this talk, I will discuss X-ray diffraction, Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, impedance spectroscopy, and thermal gravimetric analysis used to understand the characteristic changes of zirconia powders as a function of temperature and relative humidity.
