摘要：

A new high temperature Nuclear Magnetic Resonance device using double laser heating system has been developed for NMR experiments up to 1500 degrees C. Difficult systems have been investigated, both of theoritical and applied interest. We report here three examples, where the appearance and the role of mobile species are characterized by Al-27, Na-23 and F-19 NMR signal evolution with temperature: solid - liquid transition in cryolite Na3AlF6, beta-alpha alumina transformation with fluoride mineralizer, and the effects of mineralizer CaF2 on the high temperature reactions in the clinker formation.
