  • Ceramic heating resistor, electrical heating element, and device for heating a fluid
    Patent number: 11153936
    Abstract: A ceramic heating resistor to be arranged in a tubular element of an electrical heating element for heating a fluid, preferably air, wherein the heating resistor can be produced by sintering a green body comprising at least one ceramic raw material. The heating resistor includes an electrically insulating component and an electrically conducting component, and the electrically insulating component forms a matrix in which the electrically conducting component is accommodated. An electrical heating element for heating a fluid, preferably air, including at least one tubular element, through which a fluid flows or can flow, and to a device for heating a fluid, preferably air, including at least one such heating element.
