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.
Claims10
A method of manufacturing a device in which a homogeneous electrical resistance layer of a resistive material having a resistivity of at least 10 ohm. cm is formed on an insulating substrate, characterized in that from a stable binder-free suspension containing ruthenium hydroxide and glass particles a layer is provided on the insulating substrate from which an electrical resistance layer, which contains 1-6 percent by weight of ruthenium oxide, is formed by heating.
