Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The results of impurity composition determination in lead tungstate raw material and in the scintillation single crystals at various stages of the technological process are presented. Iron content in the samples was determined by extraction photometry after the double-stage sample breakdown. AI, Bi, Сг, Сu, Mg, Mn, Mо, Ni, Si, Sn, and Ti were determined by atomic emission spectroscopy under arc excitation. The revealed differences in the concentration levels of the above-listed impurities in colored and colorless crystals have been demonstrated to be insufficient for make any substantial effect on the crystal light absorption. These differences have been supposed to be caused by formation of intrinsic impurities in the course of the raw material solid-phase synthesis. |
