Descrição

Hexagonal compounds of formula Zr6FeX2 were prepared and studied by X-ray and neutron diffraction and by 57Fe Mössbauer spectroscopy. The first results indicate that most of the compounds can be prepared mainly as a single phase after at least 5 weeks of annealing at a temperature close to 900 °C. In particular, the hyperfine parameter distributions in Mössbauer spectra reflect the ability to form pure phases. http://www.sciencedirect.com/science/article/B6TWY-4KXDWF9-4/1/9d2fe798d72e4ef53fbe83343d6a1568
