Abstract

Viscosity and density of molten germanium have been measured with an oscillating viscometer and a pycnometric densitometer in a wide temperature range. The viscosity obtained represents a good Arrhenian straight line in spite of such a wide temperature range. The behaviour is different from the reported values, which show a non-Arrhenian relationship and lower viscosity, especially in the higher temperature range. The density obtained shows a good linear relationship with temperature and the expansion coefficient is almost the same as literature values although the reported values are different from each other. Present results were discussed by comparison with the behaviour of molten silicon.
