An Investigation on the Valency State of Molybdenum in Glasses with and without Fission Products
Transition elements appear in glass and ceramics in several oxidation states, which depend on composition, temperature and atmosphere. Structure and properties of these elements depend on the oxidation states. Investigations have shown that borosilicate glasses, which contain fission products and are melted in an oxidizing atmosphere, sometimes show separation of alkali molybdates. If these glasses are melted under reducing conditions (1), the solubility of the molybdenum increases. Knowledge of state and structure of molybdenum in glass is therefore highly significant. As yet, investigations in this direction are limited. References 2.–7. deal solely with phosphate glasses with the exception of 3. In the present work, the state of molybdenum in silicate glass is studied by ESR and optical spectroscopy, aiming to clarify the following:
Oxidation states of molybdenum and its reactions a) under oxidizing, b) under reducing conditions and c) as a function of molybdenum concentration.
Reaction of the molybdenum oxidation states with iron.
