“…11 Details on this technique were presented elsewhere. 12,13 The viscosity measurement was performed with the previously developed oscillating sphere method, displaying a precision of ± (2-3%). 11 Details on this technique were presented elsewhere.…”

“…11 Details on this technique were presented elsewhere. 10,[13][14][15] For both experimental measurement, density and viscosity, were used vertical furnaces working in argon controlled atmosphere. A constant temperature of the furnace within ± 0.2 °C was ensured during measurements.…”
