摘要： A support crucible includes a central axis, outer radii including longest outer radii defining planes with the central axis, a side wall region having a circumferential direction and a bottom. At least two neighboring segments are separated by joints extending substantially vertically in the side wall region to the bottom and penetrating the bottom. The joints define opposed surfaces of the neighboring segments which always overlap each other in the circumferential direction of the side wall region in an operating state. Each of the surfaces is intersected by a respective one of the planes, at least in the side wall region. According to another embodiment, the joints defining opposed surfaces of the neighboring segments have complementary shapes, the surfaces are formed by cuts beginning at a jacket surface of the side wall region and extending parallel to the central axis and at an angle to the planes, and the cuts extend in a curve to the central axis. A method for producing such a support crucible includes producing the crucible segments by beginning cuts at starting points on the jacket surface to be cut apart into the segments, and directing each of the cuts parallel to the central axis at an angle to one of the planes at one of the starting points and in a curve beginning at one of the starting points and extending to the central axis.

摘要翻译： 支撑坩埚包括中心轴线，外半径包括具有中心轴线的限定平面的最长外半径，具有圆周方向和底部的侧壁区域。 至少两个相邻的部分由在侧壁区域中基本上垂直延伸到底部并且穿透底部的关节分开。 这些接头限定在工作状态下在侧壁区域的圆周方向上彼此重叠的相邻段的相对表面。 每个表面至少在侧壁区域中由相应的一个平面相交。 根据另一个实施例，限定相邻部分的相对表面的接头具有互补形状，表面由在侧壁区域的护套表面处开始并且平行于中心轴线延伸并且与平面成一定角度延伸的切口形成，以及 切口以曲线延伸到中心轴线。 用于制造这种支撑坩埚的方法包括通过在夹套表面上的起始点处开始切割来制造坩埚段，以将其切割成段，并且将每个切口平行于中心轴线指向一个平面 在起始点之一和起始点之一开始并延伸到中心轴的曲线中。
