Abstract
An internal resistive coating for a cathode ray tube is derived from a suspension which includes electrically conductive particles, electrically insulative particles, silicate solids and a wetting agent of the anionic class. The internal resistive coating is made by mixing the insulative particles, a silicate solution and water, milling the mixture, adding electrically conductive particles to the mixture, milling the electrically conductive particles and mixture to provide a suspension, preparing a stock solution of wetting agent of the anionic class, and stirring the wetting agent stock solution into the suspension to provide a wall dispersed resistive coating suspension.
