摘要： The present invention is directed to a single crystal pulling crucible of carbon fiber reinforced carbon composite material formed by the filament windings by combination of axially reinforced layers as well as circumberentially reinforced layers, which combination is given in two or more sets, and to the producing method thereof. The circumferentially reinforced layers resist a force tending to exapand a drum portion of the crucible, and the axially reinforced layers resist a force tending to push down a bottom of the crucible. The axially reinforced layers extending from the bottom portion to the drum portion can be formed by at least either of a level winding of a contact angle of 0.degree. to 10.degree. with respect to the center axis and a poral winding, and the circumferentially reinforced layers in area adjacent to the drum portion out of the drum portion and the bottom portion can be formed by at least either of a parallel winding of a contact angle of 70.degree. to 90.degree. with respect to the center axis and a helical winding. When the axially reinforced layers cover the center of the bottom portion, an integral crucible of C/C composite material with no hole is provided. When the surface of the C/C composite material is impregnated and covered with a pyrolytic carbon, improved resistance to forming SiC is provided.

摘要： Since the dense and high purity pyrolytic-carbon-coated layer is formed with a thickness of 10-100 &mgr;m on the surface of the C/C composite, even when metallic impurities of the inside C/C composite are 5-100 ppm in ash content, similar effects to those of a known crucible made of the C/C composite whose inside was subjected to high purification can be produced to achieve full applicability to the structural elements of the CZ apparatus. Also, since the process time required or the C/C composite itself to be subjected to the high purification can be shortened, the effect of reducing the manufacturing costs considerably can be obtained.
