A conductive suspension for making contact to the inside of a picture tube consists of graphite, glass-frit powder, a binder, such as nitrocellulose, a solvent, such as isoamyl acetate. It can be applied prior to or after the aluminizing process by various techniques, such as brushing, printing, or spraying, and permits the bake-out process and the frit-sealing process to be performed in one step because it is permeable to organic substances. It is easy to remove from defective tube parts by conventional cleansing techniques.
