The use of electron paramagnetic resonance in glasses and raw materials studies

The possibility of using the method of electron paramagnetic resonance in the study of the fine structure of glasses and glass-crystalline materials, as well as for the detection and identification of defects in glasses, which will increase the homogeneity of the glass and increase its operational characteristics, has been shown. The spectra of paramagnetic ions are discussed (Cu ²⁺ ; V ⁴⁺ ; Ti ³⁺ ; Mo ⁵⁺ ; Mn ²⁺ ; Fe ³⁺ ). Specific examples of the detection of these ions in sitalls, in which they are introduced as surface-active additives or are present as impurities that have entered the crystallized glass through raw materials, are considered.
