Summary

The limits of current technology are frequently set by the availability or otherwise of suitable materials. Materials may be used for constructional purposes or in more active roles as a consequence of their special electrical, magnetic, insulating, dielectric or other physical properties. Concerns are new or improved materials and their applications in electrical apparatus. Solids, liquids or gases with novel properties that can be utilised in electrotechnology. Information on the performance of these materials.
