Understanding glass and ceramic materials is based on a broad foundation of fundamental knowledge of solid state chemistry and physics. This begins with chemical bonding and the structures of ceramics and glass materials. The path from raw material to the final product is determined, on the one hand, by powder technology processing of ceramics, on the other, by glass melting and refining techniques.
Important fundamentals of chemistry of glass and ceramic materials combined with processing techniques enable the understanding of microstructure-property correlations. Mechanical, thermal, dielectric, electrical and optical properties of inorganic-nonmetallic materials will be studied in more detail in the second part of the lecture.
