Product Description

Al2O3 Metalized Ceramic Insulator for High Voltage Feedthru

We manufacture a diversity of metallized ceramic insulators with different specification, like Metallized Ceramic Tube, Metallized Ceramic Ring, Metallized Ceramic Substrate and so on. These Metallized Ceramics are made of aluminum oxide, zirconium oxide or beryllia ceramics via dry pressing, injection molding, or hot pressing.

We can proceed with small part-size to large part-size, the min. diameter can be 1mm, the largest diameter is up to 800mm. In order to meet customers' different needs, we offer a selection of types of metallization, the typical ones as below:

1. Ceramic base + Molybdenum (Mo/Mn) metallization ...................................2. Ceramic base + Mo/Mn metallization + Nickle(Ni) plating

3. Ceramic base + Silver(Ag) plating................................................................4. Ceramic base + Tungsten (W) metallization + Gold(Au) plating

We offer different grade precision Metallized Ceramic Insulator when you need these ceramic components to be very precise, these vacuum ceramic components would be further proceeded via lapping, grinding, CNC machining before metallization on site production. The finest tolerance can be +/-0.001 for length, +/-0.005 for both inner and outer diameter.

Metallized ceramics

Technical Key Parameter of metalized ceramic insulator

Cosmetic Quality:1. No cracks, no bubbles; 2. Evenly distributed glaze; 3. No contamination

Main features of Metalized Ceramics

●High bonding/brazing strength between ceramic parts and metal components

Low leakage rate and very ideal air tightness and gas hermeticity after brazing

High Insulation strength, high dielectric value which fit for high voltage and currency application

High mechanical strength, the flextural strength can be 320MPa, the hardness can be 1700HV

Low coefficient of thermal expansion, it's range from 5 ~ 8 × 10-6 /°C

●Chemical stability which can withstand any harsh enviroment in strong acid, alkali conditions

The typical application of metallized ceramic insulators

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.
