摘要：

The development of a new NMR device has been carried out to study high-temperature liquids: it includes a heating mode (CO2 laser) and a special radio-frequency (RF) coil that enables us to study aerodynamic levitating droplets which have no interaction with the nozzle; oxidizing, neutral or reducing atmospheres can be used as levitation gases. We present here Al-27 NMR results on calcium aluminosilicate melts; in all cases the narrow (200-300 Hz) resonance line shows a rapid exchange regime with a dependence of the chemical shift on the liquid composition.
