Abstract
A crucible holding member includes a mesh body, a matrix, and a carbonaceous layer. The mesh body has a cylinder shape or a basket shape and is formed by weaving a plurality of strands to be aligned diagonally with respect to an axis line of the mesh body. Each of the strands includes a plurality of carbon fibers. The matrix is filled in interstices between the plurality of carbon fibers. A carbonaceous layer is provided on an inner circumferential surface of the mesh body and has a flat surface to contact with an outer circumferential surface of a crucible.

A crucible holding member comprising:
- a mesh body having a cylinder shape or a basket shape and formed by weaving a plurality of strands to be aligned diagonally with respect to an axis line of the mesh body, each of the strands comprising a plurality of carbon fibers;
- a matrix filled in interstices between the plurality of carbon fibers;
- and
- a carbonaceous layer provided on an inner circumferential surface of the mesh body and having a flat surface to contact with an outer circumferential surface of a crucible.
A method for producing a crucible holding member, the method comprising:
- weaving a plurality of strands to be aligned diagonally with respect to an axis line of a mesh body to form the mesh body having a cylinder shape or a basket shape with a closed end, each of the strands comprising a plurality of carbon fibers;
- filling a matrix precursor in interstices between the plurality of carbon fibers;
- applying onto an inner circumferential surface of the mesh body a carbon precursor comprising a resin material with which a carbon aggregate is mixed;
- and
- curing and burning the carbon precursor to form a carbonaceous layer.
