Ceramics are inorganic, nonmetallic materials (such as carbides, oxides and nitrides) made by shaping at a high temperature. Ceramics are hard, brittle, heat- and corrosion-resistant, and most often have a crystalline structure.

    Georg Bednorz, together with Karl Alexander Müller, discovered high-temperature superconductivity (HTS) in ceramics, for which they were awarded the Nobel Prize in Physics in 1987. Christine Horejs talks to Georg Bednorz about the successes and challenges of his research on HTS, applications of HTS materials, and the key ingredients for scientific discoveries.
