Metallized Ceramic Tube
By metallizing the designated area of the advanced ceramic tube, the purpose of sealing from the ceramic to the metal can be achieved well. After high-temperature curing in a reducing atmosphere, the metallic film can adhere tightly to Ceramic parts. Then, the resulting metalized ceramic can be directly brazed with Kovar alloy, pure copper, or stainless steel components.
To increase the wettability during the brazing process and prevent the Ceramic Metallization from oxidizing, additional metal plating is usually further covered on the metallization layer, mainly including nickel plating, gold plating, silver plating, etc.
Alumina metallized Ceramic Tubes are among the most widely used technical Ceramic Components on the market. They have high bonding strength, excellent electrical insulation, and mechanical strength. In the common case, metallized ceramic tubes are related to precision fitting relationships, which means tight dimensional tolerance is required. With our well-equipped in-house CNC machining shop and skilled machining technology, we can manufacture metallized ceramic tubes in high-precision dimensions per our customers' specifications.

Joining Ceramic to Metal by Metalizing and Brazing
The properties of ceramics and metals are very different. Solders often cannot wet the ceramic surface, the matching stress is relatively large, and it is not easy to form a strong and lasting connection. Therefore, a transition layer is often used, that is, a metal film is made on the ceramic surface, and then the metal film and the metal are brazed.
The metal film on the ceramic surface can be used as a preparation for the brazing of metal and ceramic, or it can exist alone as a functional device (such as thick film circuit, thick film sensor, etc.) or component (thick film electrode, etc.).

The picture above shows a typical ceramic-metal sealing process, which is to transform the ceramic-metal sealing into metal-metal sealing by preparing metallized ceramics.
1. Prepare ceramic insulators.
2. Metallize the ceramic surface.
3. Plate a layer of Ni on the sintered metallized surface.
4. Use solder to seal the metallized ceramic with metal parts.
