C. Favotto et al., Synthesis by soft chemistry and characterization of hafnyle (IV) nitrate hydrate HfO(NO3)(2), x-H-20., ANN CHIM-SC, 26(5), 2001, pp. 71-78
This paper deals with the synthesis and characterization of hafnyle (IV) ni
trate hydrate from HfCl4. The elaboration method is a soft chemistry one wh
ich allows to obtain a pure product. The nitrate was characterized by FTIR
spectra, X ray diffraction and thermal analysis data (TDA-TGA). The degree
of hydration was determined to be 2.
