Large Size 99.7 Alumina Ceramic Seal Ring

High Hermeticity Metallized Ceramic Bushing Features: 1.Material: 96% Aluminia(AL2O3) 2.Coating Layer:Molybdenum-Mananese(Mo/Mn) 3.These metallized ceramics are ideal for high voltage, high vacuum and high pressure applicationos. So far the most widely-used and effective method for creating a leak-tight, robust joint between ceramic and metal is by brazing . A thin layer of metal deposited on a ceramic part enables brazing between ceramic and metal part that h as a different coefficient of thermal expansion. A layer of Molybdenum-Manganese is deposited with a typical thickness of 8 to 30 µm after sintering. The metallized surface receives a secondary coating of nickel to seal and improve wettability for later brazing. Applications: Electrical transmission and distribution Electronics industry Textile machinery Defense Medical electronics Automobile industry Sealing Solid Oxide Fuel Cells High temperature application

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.

INNOVACERA® Ceramic hot surface igniters for pellet boilers only need approx. 1/10 of the energy of that needed by hot air fans and ignition blowers. Their ignition capacity lies between 120 and 350 W. Depending on the positioning of the ignition element in the boiler, the ignition time of approx. 60 seconds is extremely short. This also means minimal emissions. Specification: Voltage: 120V / 230V Power: 150W / 170W / 200W / 230W Tube Size: OD10.5 × ID6.5 × L78 mm Supporting Socket: NO.7 Lead wire: 300mm / 400mm / 500mm / 900mm (Customized is accept) Range of temperature: 800~1100 °C Applications: Kerosene fan heater Wood pellet, wood chips stove or boiler Small scale biomass industrial furnace ignition Incense burner
