Electronic ceramics
Ceramics are widely used in electronics (chip packages, insulators, capacitors, resistors, inductors, fuse blocks, etc.). Here are just two examples. Ferrite is a ferromagnetic ceramic used for making things like inductors, transformers and chokes. The bulge you often find on the power or data cord to one of your computer, stereo or television devices is a piece of ferrite around the cord that blocks high-frequency signals picked up by the wire from interfering with the electronics. The two ferrite rings in this photo are about 30mm/1.2" across.
The white ceramic insulating spacers hold the fixed and the rotating sides of the variable capacitor apart from each other.
