INNOVACERA | technical ceramic solutions

  Metallization ceramic cylinders   are a crucial component of vacuum interrupters (often referred to as VI) used in the fabrication of vacuum circuit breakers (VCB). VCBs find application in medium-voltage switchgear and distribution circuits, where they play a pivotal role in regulating distribution voltage by suppressing voltage surges. Innovacera is a lead supplier of  high purity alumina metallized ceramic cylinders . These metalized cylinders are used in vacuum arc extinguishing chambers worldwide due to their excellent electrical insulation properties   Innovacera specializes in the metallization of molybdenum-manganese (Mo-Mn) and nickel plating, providing excellent hermetic sealing for these metallzed ceramic cylinders, essential components in vacuum interrupters.   The hermetic sealing ensures the maintenance of the required vacuum level for efficient arc extinguishing within the interrupter chamber. Moreover, the high mechanical strength of Mo-Mn meta...

INNOVACERA supplies custom refractory metalized alumina ceramics for use in power grid tubes, x-ray tubes, vacuum interrupters, and similar applications where ceramic-to-metal seal joints of exceptional strength and hermeticity are required. Ceramic material: Aluminum Oxide Beryllium Oxide Deposition methods: Screen printing Pad printing Brush coating A coating of molybdenum-based paint followed by nickel plating can provide an interface where the ceramic/metal component can be formed by brazing, providing a sealed joint. After sintering, a layer of molybdenum-manganese alloy with a thickness of 10–30 μm was deposited. The metallization sintering process is carefully controlled to achieve a balanced mixture of molybdenum particles surrounded by a glass matrix to insure high bond strength between the metallization layer and the ceramic matrix.
