Course on Introduction to Glass Science & Technology at IIT Kharagpur [Dec 14-18]: Register by Dec 10

About the Course

Glass is a non-crystalline, often transparent amorphous solid, that has widespread practical, technological, and decorative use in e.g. window panes, tableware, and optics. Glass is most often formed by rapid cooling (quenching) of the molten form, some glasses such as volcanic glass are naturally occurring. Soda-lime glass, containing around 70% silica, account for around 90% of manufactured glass.

The term glass, in popular usage, is often used to refer only to this type of material, although silica-free glasses often have desirable properties for applications in modern communications. The refractive, reflective and transmission proper ties of glass make glass suitable for optical lenses, prisms, optical fibers, and optoelectronics materials. When extruded as glass fiber and matted as glass wool so as to trap air, it becomes a thermal insulating material.

Course objective

The objective of the course is to provide a broad overview about glassy materials to the participants. It is an amalgamation of various scientific and technological aspects associated with the commercial production of glassy materials.

The course will first discuss about glass and their importance in modern and ancient times, how they are formed or what governs their transition to a glassy state, what are their structures in the atomic and microstructural level and how to engineer with this microstructure. It will then turn towards the commercial production of glasses with a detailed discussion about the integrated technological aspects.

Finally, it will deal with the mechanical properties of glassy materials and various ways to alter them so as to meet required property specifications. At the end, the course will shift focus to certain special types of glassy materials like bulk metallic glass, glassceramics, borosilicate glass, non-oxide glass, chalcogenide glass, optical fibres etc. The course content will be spread over 30 working hours (6 hours per day)
