Specific manufacturing method of alumina straight crucible

　　With the maturity of photovoltaic technology, the application of solar cells is also booming. Solar cells are usually formed on aluminum oxide straight crucible substrates, which can be single-crystal silicon substrates or polycrystalline silicon substrates. Currently, the general method for obtaining aluminum oxide straight crucibles is through the melting, solidification, and cutting of silicon materials. The container holding the polysilicon raw material, the general method for growing single crystals, and the Aberdeen crystal in contact with the raw material are placed in the crucible. The temperature of this melt gradually decreases in the Aberdeen crystal, growing a single crystal.

　　 aluminum oxide straight crucible What is the specific manufacturing method?

　　The connecting part of the aluminum oxide straight crucible is a transfer arc, and the bottom of the pocket is rounded. In this embodiment, the crucible body is a typical cube, such as a rectangular parallelepiped or a cube. There are several pockets at the bottom of the crucible. Silicon is mounted on the crucible body. Transition arcs are used at the bottom and sides of the crucible body and at the connection between the crucible body and the pockets, and the bottom of the pockets is rounded to avoid unnecessary losses during transportation, ensuring safety and reliability. The pockets are pockets with inclined side walls. The outer wall and bottom of the pocket form an acute angle, and the Aberdeen crystal is placed inside the pocket. The outer wall of the pocket is an entry angle, so the diameter of the bottom of the pocket is larger than the diameter above the pocket. That is, the bottom of this pocket is larger than the opening at the bottom. First, the Aberdeen is inserted at an angle and then placed at the bottom of the pocket. This structure greatly prevents the Aberdeen from jumping out of the pocket and escaping. In addition, transition arcs are used at the bottom and sides of the aluminum oxide straight crucible body and at the connection between the crucible body and the pockets, and the bottom of the pockets is rounded to avoid unnecessary losses during transportation, ensuring safety and reliability.

　　 aluminum oxide straight crucible The lower and side parts of the crucible body are transition arcs, and the lower part of the crucible body includes multiple pockets to prevent floating. The corresponding body and corresponding pockets will all be shown. The pockets are pockets with inclined side walls. The outer wall of the pocket forms an acute angle with the bottom. The bottom of the pocket is rounded. The connecting part of the body and the pocket is a transition arc. The advantages of this utility model are that the use of tungsten with pockets and transition arcs prevents fluctuations and unnecessary losses during the actual process of crystal growth, ensuring safety and reliability.
