Metallized Ceramic Insulation Tube for High Voltage Feedthrough
Metalized ceramics are widely used in electronics, high-vacuum technology, sensors, and medical fields, like vacuum interrupters, electron tubes, feed-throughs, medical linear accelerators/ power tubes, photomultiplier, X-ray tubes, and pressure sensors.
In the ceramic-to-metal joining technology, a certain metallic layer on the ceramic surface is needed, like Molybdenum or Tungsten, then it could be achieved in connection of metal and ceramic using high-temperature brazing. Metalized alumina Ceramic Parts are commonly used in many applications, like electronics, High-Vacuum Technology, Medical Technology, and Sensor Technology.
The metalized alumina ceramic parts we manufacture are famous for their excellent bonding strength, super mechanical, excellent electrical insulation, and exceptional thermal features.
Standard types of metalization
1. Alumina ceramic base + silver (Ag) plating directly 2. Alumina ceramic base + molybdenum (Mo/Mn) metallization
3.Alumina ceramic base + molybdenum (Mo/Mn) + nickel (Ni) plating 4. Alumina ceramic base + tungsten (W) metalization + gold (Au) plating
