GRWAY® Double power Ceramic Heating Element were Alumina heater produced by implementing ceramic lamination processes. Due to the compactness, high power and rapid heating speed .Ceramic Heater can provide higher reliability than ever before. Mainly applications include use as innovative types of heaters in the automotive, medical and semiconductor industries.
First, painting the high melting point metal (tungsten or molybdenum manganese) paste on to the Al2O3 casting briquette in coordinate to the circuit design, then another layer of sintering additives. After that, repeating the process to build multiple layers. Then, they are sintered together under 1600°C hydrogen gas environment. Finally, nickel leads are brazed at 800°C onto the metal end and put on with Teflon sleeve, which make it a MCH heating element.
Internal Heating elements are protected from oxidation due to sintering into one-piece ceramic body structure.
