本发明涉及一种电子管栅极的制造方法,通过含碳气体的热分解使热解石墨沉积在芯模上,把由此构成的坯体与芯模分离,就具有栅极的形状和尺寸。石墨作为一种材料,已经在充气管或高真空的管子中获得了广泛应用。决定石墨在这些
The present invention relates to a method of manufacturing a gate of an electron tube having a gate shape and size by depositing pyrolytic graphite on a core mold by thermal decomposition of a carbon-containing gas and separating the thus-formed body from the core mold. Graphite, as a material, has gained widespread use in inflated or high vacuum tubes. Decide on graphite in these
