Metallized Ceramic Vacuum Interrupters

FUBOON suppliers precision Big Diametre Glazing&Metallized Ceramic Tubes in alumium oxide ceramics for the military,medical and aerospace industries.Through spray,needle and brush coatings or screen printing our capabilities allow us to metallized on flat,cylindrical and complex ceramic bodies. Moly-Manganese is the typical base coat materials used for metallization.

Overview of Main Physical Properties:

1.Good electrical insulation

2.High mechanical strength

3.Excellent wear resistance

4.Excellent corrosion resistance

5.Low dielectric constant



Product Description
1) High-intensity sealing, high air-tightness, high reliability, good heat resistance
2) Excellent insulation performance and high temperature resistance
3) Good mechanical , electrical and thermal conductivity
4) Great bonding strength
5) Widely used for all electric products and electric heating products1.Material: 96% Aluminia(AL2O3)
2.Coating Layer:Molybdenum-Mananese(Mo/Mn)
3.These metallized ceramics are ideal for high voltage, high vacuum and high pressure applicationos.

So far the most widely-used and effective method for creating a leak-tight, robust joint between ceramic and metal is by brazing
. A thin layer of metal deposited on a ceramic part enables brazing between ceramic and metal part that h as a different
coefficient of thermal expansion.
A layer of Molybdenum-Manganese is deposited with a typical thickness of 8 to 30 µm after sintering.
The metallized surface receives a secondary coating of nickel to seal and improve wettability for later brazing.
