A high‐temperature centrifugal‐filtration apparatus is described for separating the liquid phase from the solid phase in a fused salt system. The filtrate can be observed as it is obtained while the sample is maintained in a controlled atmosphere. The application of this apparatus to a phase rule study is demonstrated by locating the invariant point between the compounds LiF and Li 2 BeF 4 in the binary system LiF‐BeF 2 at 66.7 ± 0.8 mole % lithium fluoride and 456°± 2°C.
