Title:

ELECTRICITY INTRODUCING MEMBER FOR VESSELS

Document Type and Number:

WIPO Patent Application WO/1999/013493

Kind Code:

A1

Abstract:

An electricity introducing member for vessels comprising a closing member and an electrode core formed integrally together, wherein: a plurality of layers each comprising a conductive component and silica, the volumetric proportion of the silica being n1, n2, n3, ---, nx (n1 > n2 > n3 > ... > nx), are successively laminated in the form of a cylinder, so that the closing member serves as a functionally gradient material; when the diameter of the closing member is D (mm) and the total thickness of the laminate of the layers each containing more than 80 volume % of silica is L (mm), then L/D is not smaller than 2; the electrode core is shrinkage-fitted from the surface on the side of the layer n1 up to the layer containing at most 80 volume % of silica in the closing member; and when the diameter of the electrode core is d (mm), d/D is from 0.12 to 0.6.
