Within the framework of dissemination and collaboration of the project, throughout the months of November and December 2021, various contacts and meetings have been held between the technical responsibles of INSERTEC and the technical responsibles of Magnesitas de Navarra (LIFE REFRACT5 project) with the aim of exchanging experiences, updating the situation and progress of the projects,  share concerns and difficulties in their development and find ways of collaboration. They have been very fruitful exchanges in which different aspects of the projects have been discussed and in which knowledge about materials, processes, etc. has been expanded and strengthened
