Crystalline phase detection in glass ceramics by EPR spectroscopy
The advances of EPR spectroscopy for the detection of activators as well as determining their local structure in the crystalline phase of glass ceramics is considered. The feasibility of d-element (Mn²⁺, Cu²⁺) and f-element(Gd³⁺, Eu²⁺) ion probes for the investigation of glass ceramics is discussed....

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The advances of EPR spectroscopy for the detection of activators as well as determining their local structure in the crystalline phase of glass ceramics is considered. The feasibility of d-element (Mn²⁺, Cu²⁺) and f-element(Gd³⁺, Eu²⁺) ion probes for the investigation of glass ceramics is discussed. In the case of Mn²⁺, the informationis obtained from the EPR spectrum superhyperfine structure, for Gd³⁺ and Eu²⁺ probes – from the EPR spectrum fine structure, whereas for Cu²⁺ ions the changes in the EPR spectrum shape could be useful. The examples of EPR spectra of the above-mentioned probes in oxyfluoride glass ceramics are illustrated.
