The first part of this monograph consists of a discussion of the microstructures of molten silicates and other inorganic substances. It is made up of seven chapters. Chapter 1 considers developments in ion-cluster theory. Chapter 2 introduces experimental approaches to the direct monitoring of a molten sample, such as hightemperature Raman spectroscopes which have successfully recorded Raman spectra from melts at temperatures of 2000K or more. Chapter 3 shows that five types of Si-O tetrahedron are appropriate microstructural units for setting up structural models. Chapter 4 confirms the SiOT model as being the primary ion-cluster theory for the efficient and reliable description of high-temperature Raman spectra. In Chapter 5, the CEMS model is created in order to interconnect microstructures and thermodynamic properties - with no adjustable parameters. Chapter 6 discusses the applicability of ab initio calculations. The Raman spectra of other inorganic compounds are shown in Chapter 7, and the use of Raman spectra to study phase transformations and solid/melt interfaces is also discussed.
