Saint-Gobain is a producer, processor and distributor of materials (glass, ceramics, plastics, cast iron, etc.) among which glass plays a key role. Saint-Gobain transforms raw materials into advanced products for use in daily life, and develops new materials for the future. Saint-Gobain operates in 46 countries worldwide, is one of the world’s hundred leading industrial corporations, and fields a workforce of over 170,500. Saint-Gobain spends some 300 million Euros in research and development, and about 3000 people are working in the 16 research laboratories supplemented by a large number of development units. The joint laboratory SVI between Saint-Gobain and CNRS is a fundamental research laboratory in the field of materials science. It aims at doing research of academic nature, focusing on the relation between materials properties and the elaboration process and is therefore developing original ways to process materials as well as new characterization tools or measurement methods.
