Abstract
PURPOSE: To prevent deterioration of insulation even when a sheathed heater is used at high temperature by using a mixture of magnesia and manganese dioxide as the insulation filler for the sheathed heater.
CONSTITUTION: A mixture of magnesia and manganese dioxide is used as the insulator for a sheathed heater. When the sheathed heater is heated at high temperature, manganese dioxide dissociates to generate oxygen so that an oxide layer is always formed on the surfaces of the sheathed heater even when the heater is completely sealed. Thus deterioration of insulation is prevented.
