PRECISE MEASUREMENTS OF VISCOSITY AT TEMPERATURES UP TO 1100 C IN IONIC MELTS,

Abstract

An extension of the theory of the oscillating cruucible gives an equation which is particularly useful as an absolute method for viscosity calculation. While more complex in theory, the oscillating crucible possesses useful advantages for high temperatures, namely the features of a small flat temperature zone, and of a complete sealed sample container. Use of a closely fitting liner in the crucible offers a further advantage in that an exchange of the melt container is possible without any changes in the experimental assembly. Results are reported for a number of 'reference' liquids at 25 C and 440 C (KNO3), and for CaCl2 (785-970 C) and BaCl (958-1040 C). (Author)
