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. It is a new type of high efficient heating elements, which can save more than 20%-30% power effect compare to PTC ceramic heaters. Our alumina ceramic heaters have many excellent features that do not exist in the sheath heaters: 1. High power density, excellent thermal efficiency 2. Rapid heating, non-hotspot temperature distribution 3. High temperature, small size, light weight 4. Excellent insulation (the leakage current is 0.5 mA under voltage 4500V/1S testing with no breakdown) 5. High reliability, stable resistance, no electric noise 6. Good chemical resistance 7. full compliance with EU RoHS (no lead, cadmium, mercury, hexavalent chromium, PCBS, and other harmful substances) 8. No charge on surface and safe to touch. The MCH is widely used in all kinds of applications nowadays, such as: intelligent bidet seat, electric water heater, medical machine, dryer, electric heating splint, electric iron, vacuum flask, electric cooker, electric bonder, capper, UTR cylinder condensation-proofer, IR physiotherapy equipment, intravenous injection heating, quick food heating, mini thermostatic bath for special crystal parts, automatic exhaust oxidation sensors, industrial equipment heater, and small heating appliance, etc. Meanwhile, it is also perfect for scientific research in lab environment due to its small size, high power density, high temperature and excellent insulation. 1. Please see images and options above for variations: 1) Model: Shape: Disk, OD:Outer Diameter, T: Thickness, V: Operation Voltage for Heating element. 2) Temperature: Heating Temperature 2.The corresponding resistance of the heating element is shown in the following table: heating element model Resistance Heating temperature O16xT1.3mm(5V) 0.9-2? ~300C O24xT1.3mm(5V) 0.8-2? ~300C O24xT1.3mm(12V) 4-6? ~300C O24xT1.3mm(24V) 9-15? ~300C O26xT1.3mm(12V) 4-6? ~300C O26xT1.3mm(24V) 10-16? ~300C O40xT1.3mm(12V) 4-6? ~300C 3. High power density, excellent thermal efficiency 4. Rapid heating, non-hotspot temperature distribution 3. High temperature, small size, light weight 5. Excellent insulation 6. High reliability, stable resistance, no electric noise 6. Good chemical resistance 7. full compliance with EU RoHS. The temperature can reach 200 C in seconds and 500 C in 30 seconds, the max and steady temperature can be up to 300-600 C which depends on the heat sink. Ceramic heater pass 60 minutes 'ON', 60 minutes 'OFF' for 1000 cycles life test at around 280 C. Perfect for scientific research in lab environment due to its small size, high power density, high temperature and excellent insulation.
