High Purity 99.99% Pyrolytic Boron Nitride PBN Ring

Pyrolytic boron nitride is a grade of hexagonal boron nitride. It is produced by chemical vapor deposition process to create its solid body and all the boron nitride crystals grow parallel to the surface of which the vapor is deposited on. Due to the nature of CVD process, PBN parts generally are requested the wall thickness not more than 3mm. PBN is also a good choice for extremely high purity of boron nitride. 99.99% is the typical grade. The CVD process give this pyrolytic boron nitride almost perfect layered structure, which leads to nisotropic thermal conductivity, making it an ideal material to make crucibles for crystal growing. PBN Ceramic Applications： -Crystal growth (VGF, LEC Crucible) -Molecular Beam Epitaxy(MBE) Crucible -MOCVD Heater -PBN Infrared Window -Traveling Wave Tube (TWT) (PBN Support Rod) -PBN Coating Graphite -High temperature, vacuum equipment insulator

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
