Viscosity Measurement at the International Conferences on Molten Slags and Fluxes from 1980 to the Present

Many papers have been presented, and the sessions well attended, on the viscosity measurements of silicate and calcium ferrite based slag systems since this conference series inception in 1980 in Halifax. Over the years, the emphasis has been spent on developing reliable measurement techniques of pure liquids, trustworthy datasets, extending the slag systems and the number of components in the liquids, understanding the behaviour of amphoteric oxides, and extending measurements to two phase systems.This paper reviews the viscosity measurement papers presented at Halifax through to Beijing, with the view to showing how the understanding and practise of viscosity measurement has changed, along with our understanding of the nature of the liquids being measured and ultimately mathematically modelled. Much of the development can be attributed to Professor Ken Mills, and this review attempts to pay tribute to his outstanding contribution to the field.
