Description

Technical Field

[0001] The utility model relates to the technical field of graphite crucibles, in particular to a hoisting graphite crucible. Background Art

[0002] With the rapid development of the semiconductor field, SiC materials are considered to be ideal materials for the third generation of semiconductors because of their advantages such as large bandgap, high thermal conductivity, large electron saturation drift rate, high critical breakdown electric field, low dielectric constant and good chemical stability. With the development of single crystal technology, the market demand for high-purity silicon carbide polycrystalline powder is growing. At present, high-purity silicon carbide polycrystalline powder is generally prepared by carbon thermal reduction and solid phase sintering. High-purity graphite crucibles are usually used as reaction vessels. The existing graphite crucibles are used by loading. The crucible is placed in the hot field by a crucible clamp. The clamp is usually a metal clamp. The friction between the inner support rod and the inner wall of the crucible is used to lift the crucible. It is easy to contaminate the system during the lifting process, and as the crucible volume becomes larger, the requirements for the clamp will also be higher. Utility Model Content

[0005] Preferably, a limiting block is fixedly connected to one side outer wall of the crucible body, a notch is provided on one side outer wall of the limiting block, and the locking block is clamped on the limiting block.

[0006] Preferably, a sealing block is fixedly connected to the lower surface of the upper cover, and the sealing block is sleeved in the crucible body.

[0007] Preferably, a stud is fixedly connected to an outer wall of one side of the lifting ring, a screw hole is opened on the upper surface of the upper cover, and the stud is threadedly connected to the screw hole.

[0008] Preferably, a hanging hole is provided on an outer wall of one side of the hanging ring.

[0009] Compared with the prior art, the beneficial effects achieved by the utility model are: the utility model uses a novel design with a hoisting structure, which can conveniently and quickly transfer the graphite crucible, and the rotating clamping fixing structure used replaces the traditional internal supporting metal clamp relying on friction, which is safer and more reliable to use, and avoids the situation where the clamp contaminates the system during the hoisting process.
