More Information
Summary:A crucible holder made of a carbon material for use in crystal pulling operations and in the shape of a hollow receptacle. The holder includes at least two distinct and complementary parts that can be brought together by junction surfaces. When the parts are assembled to form the crucible holder, specific portions of the junction surfaces overlap to form at least one overlap area. The crucible holder can limit chemical reactions between the crucible and the holder and prolong the lives of both.
