Abstract

Zr:W:Si. The optimum gel was prepared using the molar ratio 1:1:7 at pH 8. The ZrSiW gel was investigated by FTIR, XRD, thermal analysis (TGA and DTA), FESEM, XRF, and NAA. Then, XRF and NAA techniques were used to estimate the proportion of the constituents of the gel according to the molecular formula [ZrO(Si(WO))16HO]. W/Re generator was prepared based on the selected ZrSiW gel, which gives the highest tungsten content (393.3 mg W/g gel) with 75 ± 3% elution yield of Re. Quality control was studied on the Re to make sure its validity for clinical applications.
