Corning officials say the smooth surface of the ceramic disk creates only one-tenth the wear of an aluminum one.

Sitting like a plug in the tube is a porous ceramic disk made of a rhodium-cerium catalyst material.

Some faucets may have pairs of ceramic disks and rubber O-rings instead.

Its two ceramic disks did give a sharp edge to my knives, though.

Those ceramic disks in there are vibrating over five million times a second.

Examples include baskets with cloths, ceramic disks, or cabinets placed over a heat source such as steam radiators.

Beneath these there should be either tiny metal springs or small ceramic disks and rubber O-rings.

A porous barrier or ceramic disk may be used to separate the two solutions while allowing ion flow.

The ceramic disk is held in place with mounting screws (some faucets have as many as three).

This is very damaging to an insulator, and may shatter brittle glass or ceramic disks, resulting in its complete failure.
