Abstract

The invention discloses a method for manufacturing electrothermal functional ceramic through a vacuumizing method. The method comprises the steps that a ceramic precursor is subjected to pressing forming to obtain a blank body firstly, then the blank body is overall placed into a carbon-containing polymer solution, then the space where the blank body and the carbon-containing polymer solution coexist is vacuumized till the carbon-containing polymer solution permeates into the blank body so as to obtain a dipped body, then the dipped body is taken out from the carbon-containing polymer solutionso as to obtain a formed body, then the formed body is fed into a ceramic kiln to be sintered under the oxygen isolation condition so as to obtain a product, and a manufacturing material of the ceramic precursor is ceramic paste, or ceramic powder or a mixture of the ceramic paste and the ceramic powder. The electrothermal functional ceramic is high in electrothermal utilization rate and convenient to construct and apply, and the whole product can conduct electricity, and heating is uniform.

Description

technical field [0001] The invention relates to a production process of functional ceramics, in particular to a production method, product and application method of vacuum-pumped electrothermal functional ceramics, which are particularly suitable for enhancing heat conduction efficiency and improving electric heating utilization. Background technique [0002] Functional ceramics refer to ceramics whose non-mechanical properties are mainly used in applications, and usually have one or more functions. [0003] In traditional underfloor heating, heating wires are usually buried under the tiles (the heating wires are basically composed of metal resistance wires or carbon fibers). The heating wires are energized to generate heat and dissipate the heat into the room through the surface of the tiles to heat and keep the room indoors. The problems of this electric heating process are: ①The utilization rate of electric heating is not high, and interlayer thermal resistance will be fo...
