Unified International Technical
Conference on Refractories (UNITECR)

18th Biennial Worldwide Congress on Refractories

26TH – 29TH SEPTEMBER 2023

A successful event has come to an end:

1,122 participants heard the 219 lectures or had the 53 posters explained to them. We experienced four award ceremonies and events such as Young Professionals and Women@Refractories.

Networks were maintained and new contacts were made not only at the Welcome Evening or the Conference Dinner.

But everything in Frankfurt would be nothing if you hadn’t been here as our guest.
Thank you for your participation.

What remains is outstanding scientific content in the program, very good memories of the Spirit of UNITECR and the friendliness of the refractory family.

The lectures are summarized in the proceedings. Registered participants can download these 900 pages as a PDF (>300Mb).

We would be happy to make a download offer to non-participants.
