Heating resistor for ceramic heaters, ceramic heaters and method of manufacturing ceramic heaters |
摘要 |
A ceramic heater of required heating properties is made available in that adjusting elements made solid in an electric conductive element are added other than electric conductive elements of an heating resistor in a ceramic heater. Accordingly, resistance temperature coefficient is changed, not largely changing other properties of heating materials. The heating resistor may be used to a double frame ceramic heater, whereby deviations of baking conditions may be made little to heighten adherence and avoid breakage at grain boundaries
