Zusammenfassung: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)[50P2O5.3OCaO.20Na2O].xFe2O,0:5 x:5 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.
