ICTAC Certified Curie Temperature Reference Materials

ICTAC Certified Curie Temperature Reference Materials, available from TA Instruments. 

Thermal analysis systems require calibration prior to routine use. In TGA, calibration for mass is carried out by calibrating the microbalance using a set of standard weights, as for any balance system. Temperature calibration is effected by measuring the Curie point temperatures of a suite of International Confederation for Thermal Analysis and Calorimetry (ICTAC) Certified Reference Materials, which have well-defined Curie points. ...

The Curie-point flash pyrolyser was originated by Szymanski et al. [522], initially developed by Simon et al. [523] and later improved [511]. A Curie-point system (Fig. 2.24) can heat a ferromagnetic metal wire inductively with radio frequencies to the pyrolysis temperature in milliseconds. The final temperature is well characterised and reproducible. The alloy of the ferromagnetic material used achieves control of the pyrolysis temperature in a Curie-point instrument. Curie-point reference values are alumel 154.2°C, nickel 355.3°C, Perkalloy 596°C, iron 780° C, Hisat-50 1000°C. A set of six certified and traceable Curie temperature materials is available (ICTAC/TAI).
