Ronghua company in China manufactures directional ceramic envelope x-ray tube for NDT. Ceramic x-ray tube is with ceramic envelope.
Ceramic x-ray tube uses high-speed electrons to strike a metal target surface to generate electrons. According to the way of generating electrons, X-ray tubes can be grouped into two types: inflatable tubes and vacuum tubes. It contains two electrodes, an anode and a cathode. One is a filament used to emit electrons as a cathode, and the other is a target used to receive electron bombardment as an anode. Respectively used for receiving electron bombardment target material and electron emission filament. Both poles are sealed in a high-vacuum glass or ceramic housing
