Product Description

Glazed Alumina Metalized Ceramic Insulator for High Voltage Feedthrough
 

Product Description

The description of the metalized ceramics

 In the ceramic to metal joining technology, a certain metallic layer on the ceramic surface is needed, like Molybdenum or Tungsten, then it could achieve in connection of metal and ceramic by means of 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 manufactured are famous for their excellent bonding strength, super mechanical properties, 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) metallization + nickel (Ni) plating
4. Alumina ceramic base + tungsten (W) metalization + gold (Au) plating

The Prime Characteristics

The prime features of alumina metalized ceramics

1. High bonding/brazing strength with ideal vacuum tightness between the assembly
2. With diamond-like hardness to be 85 HRV and superb compressive strength 
3. Great insulation strength and volume resistivity that is suitable for various high-voltage, high-current applications     
4. Chemical stability, anti-aging, even if it works in a variety of harsh environments, is free of rust forever.
5. Over 276 times wear resistance in comparison with stainless steel, which leads to a long service lifespan.


The typical application of metalized ceramics
Remark:
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, photomultipliers,
X-ray tubes, and pressure sensors
