Nonconductive

Electrical contacts can be affected by corrosion of surfaces, and by deposition of soot and other conductive particles or nonconductive layers on or across the contacts.

Ferrite is a ceramic ferrimagnetic material that is nonconductive, so eddy currents cannot flow within it.

In electronic devices, the tiny and delicate active components are embedded within nonconductive epoxy or phenolic plastics, or within baked glass or ceramic coatings.

Nonconductive specimens tend to charge when scanned by the electron beam, and especially in secondary electron imaging mode, this causes scanning faults and other image artifacts.

The nonconductive boards support layers of copper foil conductors.

The robot would then cast most of the parts either from nonconductive molten rock ( basalt ) or purified metals.
