Welcome to the International Confederation for Thermal Analysis and Calorimetry (ICTAC)

ICTAC is a Confederation of National or Regional Thermal Analysis and Calorimetry Societies. 
The aim of ICTAC is to promote international understanding and cooperation in thermal analysis 
and calorimetry through the organization of international congresses and the work of its scientific 
committees.

ICTAC originated as ICTA, the International Confederation for Thermal Analysis, which was formed
at the First International Conference on Thermal Analysis, held in Aberdeen, Scotland, in September
1965. In 1992, the name was changed to International Confederation for Thermal Analysis and 
Calorimetry to reflect the close relationship between thermal analysis and calorimetry.

The Confederation has 24 Affiliated National or Regional Societies with a combined membership 
of over 5000. In addition there are some 500 individual members of ICTAC. Membership is open to 
everyone regardless of scientific discipline. 










Obituary Note: Prof. Sergey Vyazovkin

The ICTAC community is deeply saddened by the passing of our esteemed colleague and friend. Throughout many years of dedicated service to the International Confederation for Thermal Analysis and Calorimetry (ICTAC), he made important contributions to our scientific community, particularly through his active involvement in several ICTAC scientific and kinetics committees.

His scientific insight, commitment, and collegial spirit greatly benefited the field of thermal analysis and calorimetry, as well as the many colleagues who had the privilege to work with him.

On behalf of ICTAC, we extend our sincere condolences to his family, friends, collaborators, and all who knew him. He will be greatly missed by our community.

A full obituary has been published in Thermochimica Acta (https://doi.org/10.1016/j.tca.2026.180280).
