Boron nitride can be long-term used at 1800 degrees under vacuum atmosphere. With gas protection, Boron Nitride can be used at 2100°. Boron Nitride is with high thermal shock resistance, no cracks under extreme cold & high temperature. If you take out Boron Nitride from 1000 degree furnace and colding it within short minutes. It still won't break even repeat this test with 100 times. Material Properties: * High thermal conductivity * Excellent thermal shock resistance * Low thermal expansion * Exceptional heat resistance * Good Chemical Inertness * High electrical resistance * Low dielectric constant and loss tangent * High volume resistivity * Excellent machinability Grades 5 grades of boron nitrides are involved in Boron Nitride product series. * BN99 ● CABN ● ALBN ● ZRBN ● ZABN ● SB

At present, conventional insulation materials have disadvantages such as low temperature resistance, low purity, gas release at high temperature, poor toughness, no insulation at high temperature, and easy to be corrosed. PBN insulation board can solve these problems. Main Features: 1. The maximum tolerance is 2300℃ in vacuum and 2700℃ in ammonia atmosphere; 2. High purity, high temperature does not release gas impurities (>99.99%); 3. Good toughness (hexagonal structure similar to graphite); 4. High temperature insulation (volume resistivity 3.11×1011 ω •cm); 5. Intensification of inert, acid, alkali, salt and organic solvent corrosion; 6. Low thermal conductivity in the DIRECTION of C can block the downward conduction of heat and reduce heat loss PBN Plate Applications: For vacuum, high temperature, MBE equipment and other fields of insulation gasket, gasket, support, etc.

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
