Mo Mn Ceramic Feedthrough Ceramic Vacuum Electrodes The Ceramic Surfaces for Brazing, the surface must be metallized. Compare to Glass seal, Ceramic seal has exceptional resistance to thermal and mechanical shock as well as corrosion. While it requires more complex manufacturing processes and sophisticated engineering, the price is obviously higher. Advantages of Ceramic-to-Metal Seals * More solid, durable hermetic seal and better electrical insulation * Used for more harsh conditions, such as high and low (cryogenic) temperature, corrosive, high pressure, and high vacuum environments * High mechanical strength, less fracture when applied to high vibration and high g-load conditions * Shows strong bond and an excellent seal with metals and alloys, such as copper and Cu alloys (CuNi) and to nickel and Ni alloys.

AMB (Active Metal Brazing) is for joining ceramics that are not wetted by 'conventional' brazes.By applying active metal like titanium to be added to the braze alloy, to achieve chemically reacts with the surface of the parent ceramic.Due to the coefficient of thermal expansion of Al2O3 (7.1 ppm/K), Si3N4 (2.6 ppm/K) and AlN (4.7 ppm/K) is close to that of silicon (4 ppm/K), Direct Bond Copper (DBC) and AMB are suitable substrates for robust packaging of bare dice since such assemblies.AMB is the promising thick film technology which can be applied to Power Electronics, Automotive Electronics, Home Appliances, Aerospace, Others. INNOVACERA provide DBC, DPC, and AMB technology for customized ceramic substrates, welcome to consult more.

Metallized Ceramic Componenets: Innovacera supplies precision metallized ceramic parts in aluminum oxide ceramics for the medical, and aerospace industries. Through spray, needle, and brush coatings or screen printing our capabilities allow us to metallized on flat, cylindrical, and complex ceramic bodies. Moly-Manganese is the typical base coat materials used for metallization.In order to achieve the welding between ceramic and metal, the ceramic surface firmly adheres to a layer of the metal film, which is ceramic metallization.Refractory-metalized aluminum oxide ceramics widely use in power grid tubes, vacuum interrupters, and similar applications where metal to ceramic joints of exceptional strength and hermeticity is required.

Technical ceramics are favoured in a wide range of electronics and engineering applications for their chemical and mechanical properties. Compared to metals, they are stronger in compression, especially at higher temperatures. Ceramics have a good thermal stability (i.e. a low coefficient of thermal expansion) and good thermal and electrical resistance. They are also hard, and have excellent dimensional stability. Al2O3 Properties: Excellent electrical insulation Relatively low strength and fracture toughness Resistance to wear and corrosive Excellent thermal stability Resistance to high temperatures High electrical resistivity Good chemical stability High corrosion resistance
