Abstract

We present a new method of thermal analysis based on the position change during melting of samples heated in an electromagnetic levitation coil. The temperature is measured with a two-colour pyrometer, subject to appropriate corrections. This method appears to be a useful complement to other investigations such as differential thermal analysis (DTA) or “simultaneous stepwise heating”. The technique has been applied to the determination of the melting temperatures of alloys in the Nb-rich part of the Nb-Ge system.
