Abstract
A cathode-ray tube comprising an evacuated envelope including a glass part and an electrically-conductive coating adhered to the glass part. The coating in the form of a patch or stripe consisting essentially of a major weight proportion of metallic silver particles, preferably in the form of flakes, and a minor weight proportion of lithium silicate binder. The electrically-conductive stripe or patch may be used to assure the electrical connection between an electrically-conductive metal body attached to and having a surface contiguous with a surface of the envelope and an electrically-conductive layer supported from that surface. The stripe or patch is applied from an aqueous slurry of silver particles and lithium silicate and is dried to a substantially water-insoluble, abrasion-resistant coating without or with high-temperature baking.
