Product Description

Glazed Metallized Ceramic Tubes for Power Grid Tubes

Metallized ceramic tubes for power grid tubes is commonly made of aluminum oxide ceramics, both end surface coated with a metallisation as base layer which the typical metallisation is Molybdenum- magnesia, then it should be cured in the high temperature furnace under reduced atmosphere to form a film on the specific surface, afterwards deal with electroplating.

We have been producing various of Metallized Ceramic Tube, Metallized Ceramic Ring, Vacuum Ceramic Component, Metallized Ceramic Substrate and Metallized Ceramic Insulator from different dimensions, different design, different metal coating on surface. The main shaping methods cover dry pressing, ceramic injection molding, ISO-pressing and hot pressing.

Wth small part-size to large part-size capability, the min. diameter of Metallized Ceramics can be 1mm, the largest diameter is up to 800mm. The typical plating as below:

1. Ceramic body + Mo/Mn metallization ..............................................................................2. Ceramic body + Mo/Mn metallization + Nickle plating

3.Ceramic body + Ag plating.......................................................................................................4.Ceramic body + W metallization + Au plating

5.Ceramic Substrate + copper plating
