Abstract
A large size quartz ceramic crucible comprises a crucible, wherein round chamfers are respectively arranged at four corners of the inside and four corners of the outside of the bottom of the crucible, two intersected surfaces of the crucible are circular arc transition surfaces, the crucible is square, and the thickness of the wall of the crucible is 5-8 millimeters. The large size quartz ceramic crucible has the advantages that the wall of the crucible is relatively thin, the intensity is high, and ingot casting time is shortened.
Description
Technical field
The utility model relates to the crucible technique field, especially relates to a kind of large size quartz ceramic crucible.
Background technology
Quartz ceramic crucible because its working conditions is extremely harsh, has extremely strict requirement to shake stability, dimensional precision etc. of purity, intensity, macroscopic irregularity, inner quality, high-temperature behavior, the heat of crucible when being used for the polycrystalline silicon smelting ingot casting and using.At present, the domestic research and production producer that there is no 600L * 600B * 400H～900L * 900B * 500Hmm, wall thickness 15-20mm large size quartz ceramic crucible.
The major defect that this kind quartz ceramic crucible exists and since the height of this kind specification at 400～500mm, wall thickness between 15-20mm, when using the polycrystalline silicon smelting ingot casting, during wall thickness＞2mm, the ingot casting time 2 h will be prolonged, and after highly increasing, the ingot casting time can be prolonged equally; Simultaneously, quartz ceramic crucible purity sio2＞99.95% very easily causes the impurity in the interior impurities of quartz ceramic crucible and the ingot casting liquid constantly to discharge, and causes the ingot casting loss
The utility model content
For overcoming the problems referred to above, solve long, the thicker problem that causes the ingot casting time lengthening of sidewall of crucible of crucible for smelting ingot casting time, the technical solution adopted in the utility model is as follows:
A kind of large size quartz ceramic crucible comprises crucible, and outside and inner four angles of described crucible bottom are provided with rounded corner, and the face that crucible intersects in twos is arc-shaped transitional surface.
Described crucible is square.
The crucible wall thickness is 5-8mm.
Advantage of the present utility model: sidewall of crucible is thinner, the large shortening ingot casting time of intensity.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of large size quartz ceramic crucible comprises crucible 2, and described crucible 2 bottom external and inner four angles are provided with rounded corner 3, and the face that crucible 2 intersects in twos is arc-shaped transitional surface 4.
Described crucible 2 is square.
Sidewall of crucible 1 is thick to be 5-8mm.
The above; it only is embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
Claims (3)
1. a large size quartz ceramic crucible comprises crucible (2), it is characterized in that: described crucible (2) bottom external and inner four angles are provided with rounded corner (3), and the face that crucible (2) intersects in twos is arc-shaped transitional surface (4).
2. a kind of large size quartz ceramic crucible according to claim 1, it is characterized in that: described crucible (2) is square.
3. a kind of large size quartz ceramic crucible according to claim 1 is characterized in that: the thick 5-8mm of being of sidewall of crucible (1).
