Abstract

A thermal method connects the solid-liquid surface tensionγ/s of a substance to its triple point temperature depression. Here a practical process for application of this method is described. A previous determination of the thickness of the condensate layer which does not freeze near the wall of the porous material is no longer necessary. The process is applied to some organic substances and to a metal (indium).

Zusammenfassung

Eine thermische Methode ermöglicht die Oberflächenspannungγ/s einer Substanz mit der Erniedrigung der Tripelpunkttemperatur in Bezug zu bringen. Eine vorangehende Bestimmung der Dicke der Kondensatschicht, deren Aggregatzustand sich bei Kontakt mit dem porösen Material nicht ändert, ist überflüssig. Die Methode wird auf einige organische Verbindungen und ein Metall (Indium) angewandt.

Резюме

Описаны практически е процессы термическ ого метода, связывающего поверхностное натяжение γтв.,ж. веще ства на границе разде ла твердое тело — жидкость. Преды дущее определение толщины слоя конденсата, не за мерзающего около стенок пористо го материала, не являетс я более необходимым. У казанный процесс применим к ор ганическим веществам и к металлу индию.
