摘要：

Aluminosilicate systems containing radioactivable elements (Y or Dy) and/or Fe are investigated for possible applications in internal radiotherapy and hyperthermia, or in combined therapies. The samples were prepared by sol-gel method, using two different sources for SiO2: C8H20O4Si (TEOS) and SiO2 center dot xH(2)O (silicic acid), and nitrates as sources of Al2O3, Y2O3, Dy2O3 and Fe2O3, added in different ratios. The dried gels were heat treated at 500 degrees C for 1 hour and at 1200 degrees C for 24 hours, in order to engineer their structure. The samples were studied by differential thermal analysis/thermogravimetry and differential scanning calorimetry and the results were correlated with the data obtained by X-ray diffraction analysis.
