Description
Technical Field
The utility model relates to a special push rod for a horizontal zone-melting graphite boat, and belongs to the technical field of zone-melting germanium ingot devices.
Background
The horizontal zone melting method is that according to different segregation coefficients of different materials, raw materials in a graphite boat are heated by high-frequency induction, the head raw materials are melted into liquid, a formed melting zone slowly moves from the head to the tail in a horizontal state, and impurities are melted into the melting zone and gradually brought to the tail in the process. The process is repeated for a plurality of times, and finally the high-purity material is obtained. The horizontal zone melting method is generally used for purifying materials such as germanium, gallium arsenide and the like. Taking the horizontal zone melting method for producing germanium ingots as an example, a graphite boat is usually used to zone-melt germanium material, and a semi-open graphite boat is placed in front of and behind the graphite boat (see fig. 1). During charging, the graphite boats are sequentially arranged in the quartz tube according to the figure 1, a push rod is used in the process, the push rod is used for pushing the graphite boat containing the germanium materials to a specified position in the quartz tube, and the head of the graphite boat containing the germanium materials is positioned in a right coil shown in the figure 1. The push rod (see figure 2) used at present is simple and has no horizontal calibration function, the material-containing graphite boat is pushed to a designated position horizontally by experience during use, and in order to keep the material-containing graphite boat horizontal, the push rod is required to be slow in operation, and the horizontal state of the material-containing graphite boat in the quartz tube needs to be continuously observed and timely adjusted. The process has higher requirement on an operator, not only consumes time, but also can not ensure that the graphite boat is in a horizontal state, and the problem of uneven thickness of the germanium ingot (influencing product test and quality) caused by the inclination of the pushed graphite boat often occurs at the same time.
