Abstract
A ring for an electrode includes three or more silicon members having an arc shape and a joining part joining the silicon members. The joining part contains boron oxide. A clean copy of the amended abstract is provided in Exhibit A of this preliminary amendment.
Claims12
A ring for an electrode, comprising:
- a first ring body comprising three or more first silicon members having an arc shape arranged in a circumferential direction with first abutting surfaces of each of the three or more first silicon members facing a corresponding first abutting surface of an adjacent first silicon member;
- an outer ring body comprising three or more silicon outer peripheral members having an arc shape on an outer peripheral surface of the first ring body, the three or more silicon outer peripheral members arranged in a circumferential direction with outer abutting surfaces of each of the three or more silicon outer peripheral members facing a corresponding outer abutting surface of an adjacent silicon outer peripheral member;
- and
- a joining part provided between the first ring body and the outer ring body, wherein the joining part is a layer of B2O3 and metaboric acid, and the first abutting surfaces are out of alignment in the circumferential direction from the outer abutting surfaces;
- wherein the joining part further fills a gap between adjacent abutting surfaces of the first silicon members and another gap between adjacent abutting surfaces of the silicon outer peripheral members.
