Abstract
The viscosity of sodium–borate melts containing 1 wt % mechanically activated lanthanide group REM oxide is measured in the temperature range 950–1650 K using an oscillating viscometer. The dependences of the viscosity on temperature and composition are determined. The logarithmic dependences have high- and low-temperature portions with different viscous flow activation energies. It is found that the melt structure changes as a function of composition and temperature.
