Aquadag
Definition
A colloidal suspension of purified graphite in water or another suitable liquid, used technically as a high-temperature resistant lubricant or to create thin electrically conductive layers; also, it designates the conductive protective coating applied to the inner walls of cathode-ray tubes. This structural material helps collect secondary electrons and electrostatically shields precision components.
