Resumo
The products of reaction between ZrCl4 and NaBH4 in molten potassium bromide at 740 and 800°C under an argon pressure of 4 MPa have been characterized by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, thermogravimetry, specific surface area measurements, and elemental analysis. It has been shown that the size of the ZrB2 nanoparticles obtained at 740 and 800°C is ~20 and ~30 nm, respectively.
