Alumina-ceramic-based electrical insulator, method for producing the insulator, and vacuum tube comprising the insulator
The invention relates to an alumina-ceramic-based electrical insulator, a method for producing the insulator, and a vacuum tube comprising the insulator. The electrical insulator is provided to isolate two electrodes of a vacuum tube in which a charged particle beam flows, the electrical insulation being formed by an alumina-based ceramic. According to the invention, the ceramic comprises a vitreous phase of between 2% and 8% by mass in which at least one metal oxide is diffused from a face (20) of the electrical insulator.
