This course is intended to provide the fundamental knowledge on science and technology of glass and amorphous materials, especially composed of inorganic materials. The relationship between structure and properties of these materials is explained with the correlation with the materials processing. Thermal, optical, chemical and mechanical properties are shown in detail because these materials have been widely used in industry.
Gain an understanding of the scientific knowledge on glass and amorphous materials with their wide variety of application fields.
Gain an understanding of the material processing and manufacturing methods for glass and amorphous materials.
