Abstract
Understanding of the physical and chemical properties of oxides in termes of the molecular structure is a fundamental problem for geology, ceramic science and steel making process. In this paper, examples of applications of high temperature NMR to oxides up to 1200°C are descrived to show problems and present level of understanding. 27Al NMR studies of MgAl2O4 spinel, 11B NMR relaxation studies of Na2O-B2O3 melts and 29Si NMR studies of Na2O·3SiO2 melts are discussed as examples.
