摘要：
A method of manufacturing an electrically conducting layer on an internal wall part of a cathode-ray tube wherein by the addition of an alkali or ammonium sulphate or nitrate to a suspension consisting of a conducting material and a binder, a suspension is obtained which, upon drying on the wall, provides a layer in which substantially no gas bubbles are formed during the firing of the tube.
