Abstract

The invention relates to an improved semi-cone seed crystal chuck, comprising a chuck body, wherein an air flow guide slant is arranged on the upper portion of the chuck body; a crystal pulling observation slant is arranged on the lower portion of the chuck body; chuck connecting belt mounting holes are arranged in the middle of the chuck body from top to bottom; seed crystal positioning holes are arranged below the chuck connecting belt mounting holes; the seed crystal positioning holes and the chuck connecting belt mounting holes form installation positioning channels; breathable channels are arranged at joints of the chuck connecting belt mounting holes and the seed crystal positioning holes; the chuck connecting belt mounting holes and the seed crystal positioning holes are communicated with each other to run through the chuck body; the seed crystal positioning holes consist of upper and lower through holes, the diameter of the upper through hole is 17.5 mm, and the diameter of the lower through holes is 12 mm; and the top surface and the bottom surface of the chuck body are planes. The improved semi-cone seed crystal chuck is high in stability, excellent in breathability and small in overall expansion coefficient.

Description

technical field [0001] The invention relates to a component for a single crystal furnace, in particular to a seed crystal chuck component for a single crystal furnace. Background technique [0002] The currently used seed chucks for single crystal furnaces are molybdenum chucks, and the structures of the molybdenum chucks are different according to the types of seed crystals. The semi-conical seed crystal chuck is mainly composed of a seed crystal channel and a positioning hole. The seed crystal is installed in the cylindrical channel and fixed by a positioning pin. Since the chuck body is made of molybdenum, this connection method is easy to drop, so It affects work efficiency, wastes production resources, and does not meet the actual use requirements. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcome the deficiencies in the prior art and provide an improved half-cone seed chuck with high stability, good air permeabi...
