Abstract

Official abstract text for this publication.

A graphitization furnace includes: a first electrode; a second electrode disposed so as to face the first electrode; a first energized heating element provided on a surface of the first electrode facing the second electrode; and a second energized heating element provided on a surface of the second electrode facing the first electrode. The first and second energized heating elements are configured to allow to be disposed therebetween, an object to be processed. The graphitization furnace is configured to heat and graphitize the object to be processed disposed between the first and second energized heating elements by energizing between the first and second electrodes.

First claim

Opening claim text (preview).

1 . A graphitization furnace which heats and graphitizes an object to be processed, the graphitization furnace comprising: a first electrode; a second electrode disposed so as to face the first electrode; a first energized heating element provided on a surface of the first electrode facing the second electrode; and a second energized heating element provided on a surface of the second electrode facing the first electrode; wherein the first and second energized heating elements are configured to allow to be disposed therebetween, an object to be processed, and wherein the graphitization furnace is configured to heat and graphitize the object to be processed disposed between the first and second energized heating elements by energizing between the first and second electrodes. 2 . The graphitization furnace according to claim 1 , wherein the first and second energized heating elements are configured to allow to be sandwiched therebetween, an electrically conductive crucible containing the object to be processed. 3 . The graphitization furnace according to claim 2 , wherein the first and second energized heating elements are configured to allow a plurality of crucibles to be arranged in series therebetween. 4 . The graphitization furnace according to claim 2 , wherein the specific resistance of each of the first and second energized heating elements is greater than that of the crucible. 5 . The graphitization furnace according to claim 3 , wherein the specific resistance of each of the first and second energized heating elements is greater than that of each of the crucibles. 6 . The graphitization furnace according to claim 2 , wherein a surface of the first energized heating element which contacts the crucible has a size greater than or equal to that of an end surface of the crucible which contacts the first energized heating element, and a surface of the second energized heating element which contacts the crucible has a size greater than or equal to that of an end surface of the crucible which contacts the second energized heating element. 7 . The graphitization furnace according to claim 3 , wherein a surface of the first energized heating element which contacts the crucible has a size greater than or equal to that of an end surface of the crucible which contacts the first energized heating element, and a surface of the second energized heating element which contacts the crucible has a size greater than or equal to that of an end surface of the crucible which contacts the second energized heating element. 8 . The graphitization furnace according to claim 4 , wherein a surface of the first energized heating element which contacts the crucible has a size greater than or equal to that of an end surface of the crucible which contacts the first energized heating element, and a surface of the second energized heating element which contacts the crucible has a size greater than or equal to that of an end surface of the crucible which contacts the second energized heating element. 9 . The graphitization furnace according to claim 5 , wherein a surface of the first energized heating element which contacts the crucible has a size greater than or equal to that of an end surface of the crucible which contacts the first energized heating element, and a surface of the second energized heating element which contacts the crucible has a size greater than or equal to that of an end surface of the crucible which contacts the second energized heating element. 10 . The graphitization furnace according to claim 1 , wherein the first and second energized heating elements are configured to allow to be sandwiched therebetween, an electrically conductive molded object to be processed. 11 . The graphitization furnace according to claim 10 , wherein the specific resistance of each of the first and second energized heating elements is greater than that of the molded object to be processed. 12 . The graphitization furnace according to claim 10 , wherein a surface of the first energized heating element which contacts the molded object to be processed has a size greater than or equal to that of an end surface of the molded object to be processed which contacts the first energized heating element, and a surface of the second energized heating element which contacts the molded object to be processed has a size greater than or equal to that of an end surface of the molded object to be processed which contacts the second energized heating element. 13 . The graphitization furnace according to claim 11 , wherein a surface of the first energized heating element which contacts the molded object to be processed has a size greater than or equal to that of an end surface of the molded object to be processed which contacts the first energized heating element, and a surface of the second energized heating element which contacts the molded object to be processed has a size greater than or equal to that of an end surface of the molded object to be processed which contacts the second energized heating element.
