INNOVACERA | technical ceramic solutions

The Molybdenum/Manganese metallization developed the technology on   Ceramic-to-metal brazed   assembly, which provides high mechanical strength and good electrical insulation. At the very beginning, it was used in vacuum electronic devices, gradually applied to semiconductors, integrated circuits, electric light sources, high-energy physics, aerospace, chemical industry, metallurgy, instrumentation, machinery manufacturing, and other industrial fields.   So how to choose a material becomes more and more critical for good vacuum brazing. Here we’re mainly discussing about 3 different types of materials that will be used for ceramic-to-metal. Ceramic Al2O3 BeO BN AlN Metala Kovar alloy OFC Stainless steel Mild steel Solder Ag Ag-Cu Cu AU-Cu Au-Ni   The Ceramic materials are required to be high-temperature stabilized and good thermal expansion coefficient. INNOVACERA applies mostly the Al2O3. Since ceramics will not be directly wetted, whi...

  Metallized ceramic bushings are widely used in the joining process of ceramics and metals. Ceramics have excellent insulation properties and can be well combined with metals through the   metallization   process. In addition to standard bushings, INNOVACERA is available in many custom shapes and sizes. INNOVACERA also has brazing capabilities and can provide a one-stop service from ceramics to brazed components. This serivce allows us to offer finished hermetically sealed ceramic terminals for assembly.

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.
