Abstract
In this research we have used vibrational spectroscopy to study the phosphate mineral kosnarite KZr2PO43 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 1026 cm−1 assigned to the symmetric stretching vibration of the PO4 3− ν1 symmetric stretching vibration The series of bands at 561 595 and 638 cm−1 are assigned to the ν4 outofplane 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 ν2 inplane 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 spectroscopyThe financial and infrastructure support of the Discipline of Nanotechnology and Molecular Science Science and Engineering Faculty of the Queensland University of Technology is gratefully acknowledged The Australian Research Council ARC is thanked for funding the instrumentation The authors would like to acknowledge the Center of Microscopy at the Universidade Federal de Minas Gerais http//wwwmicroscopiaufmgbr for providing the equipment and technical support for experiments involving electron microscopy R Scholz offers thanks to FAPEMIG–Fundação de Amparo à Pesquisa do estado de Minas Gerais grant No CRA–APQ0399810
