A quasi two-dimensional bubble method for surface tension and contact angle measurements at the crystal-melt interface. II. Physical realization
An experimental setup for simultaneous measurement of the surface tension of a liquid and of the contact angle at the solid-liquid interface between a crystal and its own melt, is described. The method is based on shape determination of a gas bubble captured at the crystal-melt interface inside a th...

Summary: | An experimental setup for simultaneous measurement of the surface tension of a liquid and of the contact angle at the solid-liquid interface between a crystal and its own melt, is described. The method is based on shape determination of a gas bubble captured at the crystal-melt interface inside a thin cell composed of two plane-parallel glass plates, in contact with a temperature gradient heating block. The feasibility of the method is demonstrated in the case of coumarin. |
