Abstract
The invention discloses a magnetron output window ceramic. The magnetron output window ceramic comprises a 94% alumina ceramic tube and metal coatings. The 94% alumina ceramic tube is of a hollow cylindrical structure, and the metal coatings respectively cover the end faces of the two ends of the 94% alumina ceramic tube. The metal coatings are respectively composed of a molybdenum-manganese coating and a nickel-plated layer. The magnetron output window ceramic of the invention has the advantages of simple structure, high strength, resistance to high temperature, convenient processing, good wear resistance, high welding strength, good vacuum tightness, and long service life.
