Abstract
The viscosity of some ZrF4-based melts is presented and it is demonstrated that it is possible to perform reliable viscosity studies of these highly corrosive melts. Graphite crucibles have been utilized and corrections for the meniscus and the penetration into the crucible have been performed. A general discussion of oscillating-cup viscometry is given and it is shown that the present setup can be used for determination of viscosities in the range from 0.05 to above 500 mPa·s.
