Vacuum Ceramic Component

In modern industry, Metallized Ceramic Parts are widely used in many electronic vacuum devices, such as electron tubes, high-voltage feedthroughs, high-current feedthroughs, vacuum interrupters, vacuum capacitors/thyristors, X-ray tubes and power switches.


The key to making vacuum ceramic components is to cover the ceramic surface with a metal coating to achieve vacuum tightness and sealing. In order to achieve better brazing effect, or to protect the metal layer, we usually plate other metals on the outside of the metal layer, such as nickel plating, silver plating, gold plating, copper plating, tin plating, etc. The Metallized Ceramics produced by our company have the following characteristics:


- Extremely high bond/brazing strength

- High mechanical strength

- Good vacuum tightness

- Excellent electrical insulation

FAQ

Important things you should know

Main material used in a Vacuum Ceramic Component
Alumina ceramic has become the main insulating material in a vacuum ceramic component because of its good electrical properties at high frequencies, small dielectric loss, large specific volume resistance, high strength, small thermal expansion coefficient, and low manufacturing cost.
Why metallization is needed on ceramic surfaces
Ceramics cannot be directly welded to metals. A thin metal film needs to be sintered on the surface of the ceramics, that is, metallization. Ceramic metallization methods mainly include Electroless Nickel Plating, Silver Firing, Mo-Mn, W-Au, Magnetron Sputtering Technology (Thin Film Method), etc. Currently, the Mo-Mn Method is widely used in the production and scientific research of Vacuum Ceramic Components.
Main factors affecting the quality of ceramic metallization
There are many factors that affect the quality of ceramic metallization, generally the quality of the ceramic itself, the treatment before metallization of the ceramic, the metallization formula, the particle size of the metallization powder, the thickness and uniformity of the coating, the metallization sintering temperature, atmosphere, holding time, nickel plating thickness and uniformity, etc.
How do you control quality
We mainly control from the following two aspects:1. Strict Control in Production: Products with unqualified quality are strictly prohibited from entering the metallization process.
2. 100% Full Inspection Before Shipment: Pick out products that are undersized or have metallization layer defects.
Main application areas of Vacuum Ceramic Component (1)
The 2 most common applications of Vacuum Ceramic Component are:
1. Power electronics field: representative product: vacuum switch tube. The excellent insulation of the vacuum inside the tube enables the medium and high-voltage circuit to quickly extinguish the arc and suppress the current after cutting off the power supply, thereby achieving the function of safely breaking the circuit and controlling the power grid.
Main application areas of Vacuum Ceramic Component (2)
2. New energy vehicle field: Representative products: relays. When high-voltage DC relays are loaded and broken, arcs are generated. Due to the cooling and surface adsorption of ceramics, the arcs are quickly extinguished, preventing short circuit fires in automobile circuits caused by arcs.
