Unified International Technical
Conference on Refractories (UNITECR)

18th Biennial Worldwide Congress on Refractories

26TH – 29TH SEPTEMBER 2023

Words of Welcome

“The Carbon Challenge: Steps and leaps to master the future” is our motto for UNITECR in Frankfurt. The way to carbon neutrality for our high temperature industries will keep engineers busy for many years to come.

The transformation from carbon to green hydrogen-based steel making and the replacement of fossil fuels in high temperature processes will have an impact on the refractory materials. New technologies will require new lining concepts.

Modified and new refractory lining concepts will also help to save energy and lower the carbon emissions for existing technolohies and processes.

Modern tools such as big data analysis, machine learning, and the development of suitable models will help us to increase the speed of innovation in our industry.

The Unified International Technical Conference of Refractories (UNITECR) is a biennial international conference which contributes to the progress and exchange of industrial knowledge and technologies concerning refractories according to its official By-Laws.

The German Refractory Association is pleased to host the 18th UNITECR Conference which will be held in conjunction with the 66th International Colloquium on Refractories.

The organization of UNITECR was established in 1987 in Tokyo. The official governing body is the UNITECR International Executive Board (IEB), composed of representatives of the Founding Member Organizations, the Principal Member Organizations, and certain individuals elected to the IEB as Distinguished Life Members.
