  • Patent number: 10438768
    Abstract: An anode for an X-ray tube can include one or more of an yttrium-oxide derivative, titanium diboride, boron carbide, titanium suboxide, reaction-bonded silicon carbide, and reaction-bonded silicon nitride. Upon collision with an anode, the kinetic energy of an electron beam in an X-ray tube is converted to high-frequency electromagnetic waves, i.e., X-rays. An anode from one or more of the above materials and a gradient distribution of conductive metals can reduce costs and/or weight, extend the life of the anode or associated components (e.g., bearings) and simultaneously provide a higher heat storage capacity as compared to traditional molybdenum and tungsten anodes.
