Embodiment Construction

[0011] A quartz crucible, comprising an inner layer and an outer layer, the inner layer is high-purity quartz sand, the outer layer is a quartz crucible body, the thickness of the quartz crucible remains unchanged, but from the opening of the quartz crucible to the bottom of the quartz crucible direction, the side wall of the quartz crucible body first becomes thinner and then thicker, and the high-purity quartz sand first becomes thicker and then thinner. The thickest part of the inner layer of the quartz crucible is set to 0.15 mm, and it is arranged at the silicon melt liquid level contained in the quartz crucible, and is uniformly thinned on both sides of the thickest part, wherein the thinnest and thickest parts of the inner layer are The thickness difference between the thickest parts accounts for 25% of the thickest part of the inner layer of the quartz crucible, which is about 0.11 mm.

Abstract

The invention provides a quartz crucible. The quartz crucible comprises an inner layer and an outer layer; the inner layer is high-purity quartz sand; the outer layer is a quartz crucible body; in a direction from an opening of the quartz crucible to the bottom of the quartz crucible, a side wall of the quartz crucible body becomes thin and then becomes thick, and the high-purity quartz sand becomes thick and then becomes thin. Particularly, the high-purity quartz sand is used on the inner layer of the quartz crucible so that a deformation-resisting capability is good and the deformation-resisting capability at the most thick part is optimal; when the quartz crucible is used for storing silicon liquid, the deformation rate at a silicon solution liquid level, where deformation is most likely to occur, of the quartz crucible is controlled very well.

Description

technical field [0001] The invention belongs to the field of solar photovoltaics, in particular to a quartz crucible for containing silicon liquid. Background technique [0002] Quartz crucible has the advantages of high purity, strong temperature resistance, large size and high precision, good heat preservation, energy saving, stable quality, etc., and is used more and more widely. [0003] Generally, the wall thickness of the quartz dry pot is uniform. Due to the improper charging method, the contact surface of the material obtained on the liquid level line and the quartz crucible is in surface contact. Affected the service life and safety performance of quartz dry pan. Contents of the invention [0004] Purpose of the invention: In order to solve the deficiencies in the prior art, the present invention provides a quartz crucible, which is used to solve the deformation problem of the quartz crucible when it holds silicon liquid. [0005] Technical solutions: [0006] ...
