    • Studied chemistry at the University of Gießen before moving in 1990 to the Max Planck Institute for Metals Research. In 1992 he was awarded a Ph.D. for work carried out in the group of Prof. G. Petzow on the synthesis and properties of ceramic solids in the ternary and quaternary B[BOND]C[BOND]N and Ti[BOND]B[BOND]C[BOND]N systems. He is now a member of the research staff of the Max Planck Institute, where he heads a research group.

    • Studied chemistry and materials science at the University of Stuttgart, and was awarded his Ph.D. in 1967 by this university for a thesis on the quaternary system silver–copper–zinc–cadmium based on work carried out at the Max Planck Institute for Metals Research. He carried out research at the Max Planck Institute from 1967 to 1978 before moving to W.C. Heraeus in Hanau, where he became responsible for research and development and the Department for Special Products. In 1985 he joined Hoechst AG in Frankfurt, becoming head of the corporate research division, and in 1992 returned to the Max Planck Institute for Metals Research in Stuttgart as one of the Directors. He is also professor for nonmetallic inorganic materials at the University of Stuttgart.

Abstract

The preparation of ceramic materials from preceramic compounds provides a means for the synthesis of new materials which cannot be obtained by conventional methods. An example is shown in the figure, which shows carbon-fiber-reinforced silicon carbide coated with silicon carbonitride prepared by dip-coating the substrate with a slurry made of polyhydridomethylsilazane and silicon powder. Progress and applicational examples are reviewed
