The protective tube of silicon nitride material has high thermal conductivity, high temperature resistance, corrosion resistance,non-wetting with molten metal, and electrical insulation, making it the best choice for heating body protection tubes. The advantage of the immersion holding furnace is very obvious, and in order to achieve the immersion of the heating element into the molten metal, it is necessary to have a protective tube which can protect the heating element well. Silicon Nitride (Si3N4) Characteristics: 1 Good thermal shock resistance 2 Creep resistance 3 Low density 4 High fracture toughness 5 High hardness and wear resistance 6 Electrical resistivity

Silicon Nitride (Si3N4) is 60% lighter than steel but strong enough to survive some of the most demanding applications in a variety of industries. This lightweight, the high-strength ceramic material is used as an alternative to stainless steel, super alloys, tungsten carbides, and first-generation ceramics such as Al2O3 and ZrO2. It offers excellent thermal shock resistance and high fracture toughness, compatibility with nonferrous metal melts, and improved structural reliability compared to other ceramic materials. When extreme conditions like these push equipment to its limits, Silicon Nitride (Si3N4) industrial ceramics deliver high performance where other materials fail. Typically, Heavy-duty diesel engines. Jet engine igniters. Oil wells thousands of feet underground. Applications for silicon nitride include: Foundries Electronics Oil & Gas Automotive Aerospace

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
