The Raman spectroscopy infrastructure (LabRam HR UV-Visible-NIR) to be installed will allow the identification of mineral species directly from natural rocks, as well as to obtain the characteristic Raman spectrum of new minerals, which will be correlated to the crystal structure, chemical composition and mineral phases. These spectra obtained will also contribute to the development and...
This research proposal is devoted to characterize new mineral species from Brazil and other countries through the techniques of Raman spectroscopy, X-ray and neutron diffraction and electron microprobe analysis. The Commission on New Minerals and Nomenclature (CNMNC) of the International Mineralogical Association (IMA) has being officially approved approximately 100 new species per year...
Despite its importance, there are many Brazilian occurrences of rare minerals not completely characterized. In order to deal with this issue, this project aims to identify rare mineral species from the Volta Grande pegmatites, Nazareno, MG. We will use different characterization techniques together: Raman spectroscopy, X-ray diffraction and electron microprobe.
The pyrochlore-group of minerals comprises cubic Nb-, Ta- and Ti-bearing oxides, with general formula A2B2X6Y and space group Fd3m. They are important source of niobium and tantalum and display technological importance in a diverse range of applications, including fast ion conductors, electrocatalysts, resistors, sensors and nuclear waste disposals. Several minerals and synthetic compou...
