Fine Ground Alumina Metallized Ceramic Insulator

Fine Ground Alumina Ceramic Metallized Insulator

To meet metal to ceramic  and ceramic to ceramic jointing technology, a metallic coating will be applied  on the specific surface of ceramic insulator, then it can be achieve the jointing through brazing process.  These Metallized ceramics are ideal for use within high vacuum, high voltage and high pressure applications.

We are capable of dealing with diversity of different design, complicated structural Ceramic metallization disk via machining, laser cutting and grinding, these precision manufacturing processes helps us to reach a very good accuracy of dimensional of all these Metallized Ceramic Components.

The regular type of metallization

1. Raw ceramic part + Mo/Mn metallization............................................... 2. Raw ceramic part + Silver plating

3. Raw Ceramic Substrate + Copper plating............................................4. Raw ceramic part + Tin plating

5. Raw ceramic part + Mo/Mn metallization + nickle plating.......................6. Raw ceramic part + W metallization + gold plating

Prime features of metallized ceramic insulator

1.High bonding/brazing strength after ceramic to metal assembly,  it's up to 150MPa per square millmeter

2.High intensity sealing, high air tightness, high reliability, the leak reate less than 1×10^-11 Pa•m3 / s

3.Good heat resistance, high temperature resistant,  the max. service temperature is up to 1400℃

4.High hardness, flexural strength and compressive strength, insulation strength is up to 20kV/mm (D•C)

5.Anti-chemical, anti- aging without corrosion, it won't react with most of strong acids  and akalis

Typical application of Metalized Ceramics

Widely used in vacuum interrupters, Electron tubes,Gas discharge tube, Vacuum capacitor,Vacuum thyristors, Surge arresters,Thyristor housings,Diode housings,Power grid tubes,Traveling wave tubes,Insulator rings and cylinder,X-ray tubes and so on.
