摘要： A graphite crucible (2) for retaining a quartz crucible (1) has a graphite crucible substrate (3) as a graphite crucible forming material, and a coating film (4) made of a carbonized phenolic resin and formed over the entire surface of the graphite crucible substrate (3). The phenolic resin is impregnated inside open pores (5) existing in a surface of the graphite crucible substrate (3). The coating film (4) may be formed only within a portion of the graphite crucible in which SiC formation can occur easily, not over the entirety of the surface of the graphite crucible. For example, it is possible to deposit the film only on the entire inner surface of the crucible. It is also possible to deposit the film only on a curved portion (sharply curved portion) of the inner surface, or only on a curved portion and a straight trunk portion.
