Abstract

Nanocrystalline materials which can be plastically deformed at low temperatures have revolutionized the applications for ceramics. Two methods for the production of high-tech ceramics with grain sizes of less than 1 pm are described and the quality of the materials, for example ZrO2 powder (see figure), assessed.
