The glass formation region in the system SeO2-B2O3-CuO has been determined using the melt quenching method of sealed silica ampoules. Crystallization of CuB2O4 only has been observed in a wide concentrate region near the glass formation boundary. The formation of three-component compounds was not proved. It was suggested that the section SeO2-CuB2O4 is the only quazi-binary one as a simple eutectic type. The presence of SeO3 (ν = 820 cm-1; 760-750 cm-1) units in the amorphous samples has been confirmed by IR spectroscopy. A band at 540 cm-1 appears in the spectra, which may be assigned to the CuO4 “square planar” units.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
