Abstract

Official abstract text for this publication.

A carbon heating element and a method for manufacturing a carbon heating element are provided. The carbon heating element may efficiently dissipate heat and prevent disconnection or destruction of a heating element to prolong a lifespan thereof without generating a spark and plasma under a high voltage. The carbon heating element may include carbon (C) and silicon carbide (SiC), and the carbon heating element may have a thermal conductivity of 1.6 W/m·K or more.

First claim

Opening claim text (preview).

What is claimed is: 1. A heating element for a carbon heater, the heating element substantially consisting of: carbon (C); silicon carbide (SiC); and oxygen(O), wherein a total amount of oxygen in the heating element is 2 wt. % or less, wherein the heating element has a thermal conductivity of 1.6 W/m·K or more and a specific resistance of the heating element is (11˜16) *10 −2 Ωcm. 2. The heating element according to claim 1 , wherein the SiC includes β-SiC and α-SiC. 3. The heating element according to claim 1 , wherein a degree of crystallization of the SiC in the heating element has a full width at half maximum (FWHM) value of 0.14 as a result of analyzing an X-ray diffraction. 4. The heating element according to claim 1 , wherein the heating element includes silicon oxide (SiO 2 ). 5. The heating element according to claim 1 , wherein the heating element is solid. 6. The heating element according to claim 1 , wherein the heating element is hollow.
