Abstract

Iron phosphate glasses have found in the last time technical and biomedical application due to their specific properties. The relationship between composition and structure for the glass system (100-x)[50P2O530CaO20Na2O]xFe2O3, 0 £ x £ 20 mol % Fe2O3 has been studied. X-ray diffraction, Raman and infrared spectroscopy have been used to evidence the structural changes induced by iron addition to sodium-calcium-phosphate host glass. The biological effect of the cations released from these glasses into nutrient medium of plants was tested on Phaseolus vulgaris c.v Ardeleana..
