Raman and infrared spectroscopic study of kamphaugite-(Y).

We have studied the carbonate mineral kamphaugite-(Y)(CaY(CO3)2(OH) H2O), a mineral which contains yttrium and specific rare earth elements. Chemical analysis shows the presence of Ca, Y and C. Back scattering SEM appears to indicate a single pure phase. The vibrational spectroscopy of kamphaugite-(...
