Jürgen Rödel

Jürgen Rödel (born September 17, 1958 in Hof)[1] is a German materials scientist and professor of non-metallic inorganic materials at the Technische Universität Darmstadt.

He is particularly well known for his fundamental and pioneering work on the mechanical and functional properties of ceramics. This includes his research work on the sintering behaviour of ceramics and the development of lead-free piezoceramics. Until then, lead-free piezo materials were considered impossible. Through meticulous research, he found the first lead-free systems with "Giant" elongation.[2] In 2008, he received the Gottfried Wilhelm Leibniz Prize, the highest award for German researchers, for his contributions to the development of ferroelectric functional ceramics, new lead-free piezoelectric ceramics and novel gradient materials.[3]

Life

From 1977 to 1983, Rödel studied materials science at the University of Erlangen and ceramics at the University of Leeds. Rödel received his diploma in materials science from the University of Erlangen. In 1988, he received his Ph.D. in materials science from the University of California, Berkeley. In 1992, he habilitated in materials science at the TU Hamburg-Harburg.[1] Since 1994 he has been professor of non-metallic inorganic materials at the Technische Universität Darmstadt.[4]

Work

In 2019, Jürgen Rödel has acquired the research grant Reinhart-Koselleck project funded by the German Research Foundation (DFG). It was the first time for the Technische Universität Darmstadt that the grant was brought to the university. With the support he is currently working on improving ceramics by disrupting their atomic structure. His team is concentrating on a type of crystal defect that, although trivial for metals, has so far seemed unthinkable for hard ceramics. The mechanical deformation of ceramics takes place under controlled pressure and temperature.[5]
