The viscosity of molten Ni80P20 was measured from 1143 to 1253 K by the capillary flow method. It can be described very well by the Vogel–Fulcher equation. When the viscosity is expressed in a reduced temperature scale which is defined as T/Tg where Tg is its glass transition temperature, it follows the principle of corresponding states, the same as other easy glass forming systems.
