20080289568 | QUARTZ GLASS CRUCIBLE, PROCESS FOR PRODUCING THE SAME, AND USE - A crucible has a structure where a layer containing a crystallization accelerating component such as aluminum or the like (a crystallization accelerating layer) is inserted inside a quartz glass layer of a crucible straight body part excepting a crucible bottom part.
