The invention discloses a corrugated pipe displacement device of a sapphire single crystal furnace, and belongs to the technical field of sapphire crystal growth. The device comprises a supporting base, a first supporting rod, a second supporting rod, an arc-shaped supporting part and a first bolt, the first bolt is rotatably connected with the supporting base, the first bolt is pivoted with one end of the first supporting rod, the other end of the first supporting rod is pivoted with one end of the second supporting rod, and the other end of the second supporting rod is pivoted with the arc-shaped supporting part; and the arc-shaped supporting part is used for clamping a corrugated pipe, so that a seed crystal rod in the corrugated pipe inclines towards one direction. The device can pushthe seed crystal rod in the corrugated pipe, so that a sapphire crystal ingot is separated from the crucible to ensure that the thermal stress of the crystal is fully released.
Description
technical field [0001] The invention relates to a bellows displacement device for a sapphire single crystal furnace, belonging to the technical field of sapphire crystal growth. Background technique [0002] Sapphire is commonly known as corundum. It has excellent optical properties, mechanical properties and chemical stability, high strength and high hardness, and can work under harsh conditions close to 2000 ° C. Therefore, it is widely used in infrared military devices, satellite space technology, Window material for high-intensity lasers. [0003] Sapphire needs to be crystallized in a high-temperature furnace. Because of its high melting point, a tungsten crucible is required to hold the raw material. When the raw material melts, it begins to crystallize. After crystallization, the crystal is separated from the crucible, and the crystal can shake freely in the crucible. When pasting, the uneven thermal stress release will cause the crystal to crack. At present, the me...
