ABSTRACT:
The invention relates to a method of manufacturing a device in which a homogeneous electrical resistance layer of a resistive material having 10 ohm.cm is formed on an insulating substrate. According to the invention a stable binder-free suspension containing ruthenium hydroxide and glass particles is provided on the insulating substrate from which a ruthenium oxide-containing electrical resistance layer is formed by heating. The method according to the invention may be used successfully, for example, in the manufacture of cathode ray tubes.
