MCH is acronym for Metal Ceramic Heater, which is made
up of high melting point metal heating resistance slurry such
as tungsten or molybdenum-manganese printed onto 96%
alumina casting ceramic green body according to the design
requirements of the heating circuit. After being laminated by
heat pressing, ceramic heaters are then formed by co-firing
ceramic substrate and metal circuit in hydrogen reduction
atmosphere protection furnace at 1650° C.
