Zirconium diboride (ZrB2) is a ultra-high temperature ceramic (UHTC) that has
properties such as ultra-high melting point (3200°C), high electrical and thermal
conductivity, high hardness (20 GPa), high elastic modulus (546 GPa), good
chemical inertness, high wear resistance, lower theoretical density (6.09 g/cm 3 ),
excellent resistance to thermal shock and oxidation with unique
physicochemical properties, which mainly depend on its microstructure such as
crystal phase, particle shape, and size, among others, with applications in
thermal protection systems such as the aerospace industry. The present work,
addresses an alternative way of producing zirconium diboride using a solar
furnace at the Renewable Energy Institute of the National University of Mexico
(IER-UNAM), obtaining a new process with low CO2 emissions to produce this
material. Zirconium n-propoxide was used as the zirconium precursor at a
temperature of 1500°C for 20 min for the formation of the zirconium diboride.
The synthesis was carried out in a solar reactor designed to work with
concentrated solar energy. The structure and morphology of the solar obtained
ZrB2 were analyzed with Fourier Transform Infrared Spectrometer (FTIR), X-Ray
Diffractometer (XRD) thermal analysis (TGA/DSC), Scanning Electron Microscopy
(SEM) and Transmission Electron Microscopy (TEM) techniques. The solar
zirconium diboride is nanostructured with nanobars morphology and high
oxidation resistance.
