摘要： An expanded graphite sheet is provided that can remarkably improve the quality and yield rate by preventing chipping and cracks in the surface in molding the sheet into a desired shape by inhibiting degradation in the flexibility while reducing the ash content to a certain degree. An expanded graphite sheet (3) has a flexibility of 25 times or greater, as determined in a flexibility test in which the flexibility is defined as the number of times the expanded graphite sheet (3) can be bent using a flexibility testing device having a rotator (2) to which one end of a plate-shaped expanded graphite sheet (3) is fixed, a weight (7) fixed to the other end of the expanded graphite sheet (3), and a bending position determining member (5) for determining a bending position of the expanded graphite sheet (3) when the rotator (2) is rotated.

摘要： A crucible protection sheet is provided that can prevent damages to an inner crucible, hinder an outer crucible from silicon-carbidization, and transmit heat from the outer crucible to the inner crucible uniformly.In a crucible having an inner crucible 2 and an outer crucible 3, the crucible protection sheet is arranged between the two crucibles and is made of expanded graphite. The planar thermal conductivity is 120 W/(m·K) or higher, the gas permeability is less than 1.0×10−4 cm2/s, and the compression ratio is 20% or higher when the sheet is compressed in a thickness direction at a pressure of 34.3 MPa. Since the compression ratio is high, the effect of preventing breakage is great when inserting the inner crucible, improving workability and preventing the inner crucible from tilting inside the outer crucible. In addition, even though the compression ratio is high, the thermal conductivity is kept to such a degree that the inner crucible can be heated uniformly, and the gas shielding capability is also ensured. As a result, the outer crucible is prevented from silicon-carbidization and thickness decrease.

摘要： A carbon crucible prevents leakage of SiO gas from a boundary portion between a straight trunk portion and a tray portion and prevents SiC formation from quickly developing. A carbon crucible (5) for retaining a quartz crucible (4) used in a metal single crystal pulling apparatus for silicon or the like has a straight trunk portion (9) and a tray portion (10) that are divided from each other. A graphite sheet (11) is disposed between the quartz crucible (4) and the carbon crucible (5) so as to cover at least a boundary portion (A) of an inner surface of the carbon crucible (5) between the straight trunk portion (9) and the tray portion (10). The graphite sheet (11) is an expanded graphite sheet.

摘要： An expanded graphite sheet with improved tensile strength is provided. By using an expanded graphite sheet with improved tensile strength as a lining for a carbonaceous crucible, a method of protecting a carbonaceous crucible is provided that reduces work hours remarkably, makes it possible to cover the inner surface of the crucible without breaking the sheet or producing gaps, and is suitable for increasing the size of the crucible, and a single-crystal pulling apparatus is also provided. An expanded graphite sheet (10) is characterized in that a reinforcing material (12) comprising carbon fibers is formed in a laminate form on at least one side of a substrate (11) made of an expanded graphite material. Another feature is interposing the expanded graphite sheet (10) between a quartz crucible and a carbonaceous crucible in which the quartz crucible is placed, to use the expanded graphite sheet as a lining for covering an inner surface of the carbonaceous crucible.
