dc.description.abstractIn this research, we have used vibrational spectroscopy to study the phosphate mineral kosnarite KZr2(PO4)3. Interest in this mineral rests with the ability of zirconium phosphates (ZP) to lock in radioactive elements. ZP have the capacity to concentrate and immobilize the actinide fraction of radioactive phases in homogeneous zirconium phosphate phases. The Raman spectrum of kosnarite is characterized by a very intense band at 1,026 cm-1 assigned to the symmetric stretching vibration of the PO4 3- m1 symmetric stretching vibration. The series of bands at 561, 595 and 638 cm-1 are assigned to the m4 out-of-plane bending modes of the PO4 3- units. The intense band at 437 cm-1 with other bands of lower wavenumber at 387, 405 and 421 cm-1 is assigned to the m2 in-plane bending modes of the PO4 3- units. The number of bands in the antisymmetric stretching region supports the concept that the symmetry of the phosphate anion in the kosnarite structure is preserved. The width of the infrared spectral profile and its complexity in contrast to the wellresolved Raman spectrum show that the pegmatitic phosphates are better studied with Raman spectroscopy.pt_BR
