Mullite

Hartmut Schneider is the head of the "Structural and Functional Ceramics" group at the German Aerospace Center (DLR), Institute of Materials Research, Koln (Germany) and is a Professor of Applied Mineralogy at the University of Hannover (Germany). He has been working on different topics of high pressure mineralogy and on refractory and ceramic materials. He is renowned for his research work in crystal chemistry, ceramics and composites of mullite, an alumino silicate of the stoichiometric composition 3Al2O3?2SiO2. Professor Schneider has published over 200 scientific and technical papers. His list of awards includes the Japanese Government Research Award, the Lilienthal Award, and the Fellowship of the American Ceramic Society.
