Abstract
The utility model discloses a crucible. The crucible is characterized in that the crucible is in an opening structure of a regular cubic, is made of highly pure quartz materials and contains more than 99.7% of silicon dioxide of material components. The crucible further comprises the components of less than 600ppm of aluminum oxide and less than 300ppm of ferric oxide, and 400-450kg raw materials can be loaded in the crucible. The crucible body has large volume and capacity as well as higher silicon material output and yield.
Description
Technical field
The utility model relates to the chemical apparatus field, concrete relates to a kind of crucible.
Background technology
At present, for the employed crucible of polysilicon fusion-crystallization, all adopt the high purity graphite material in the industry, self manufacturing cost is bigger; And the polycrystalline silicon ingot casting that goes out of plumbago crucible crystallization, its impurity content is higher, and effective yield of silicon ingot is very low, and result of use is undesirable, still can not large-scale production and application.
And existing crucible basically all is the circular or similar circular crucible of monocrystalline, and the former crucible of monocrystalline is the long brilliant principle of vertical pulling method, and this structure causes silicon output and yield lower.
The utility model content
For overcoming the problems of the prior art, the purpose of the utility model is to provide a kind of crucible, and this crucible volume is big, volume big, the output and the yield of silicon material are higher.
For solving the problems of the technologies described above, realize above-mentioned technique effect, the utility model is realized through following technical scheme:
A kind of crucible is characterized in that: said crucible becomes the cube structure hatch frame of rule.
Further, the material of said crucible is the high purity quartz material, the percentage composition of silicon-dioxide＞99.7% in the material composition of said crucible.
Further, also comprise aluminum oxide in the material of said crucible, said aluminum oxide percentage composition＜600ppm.
Further, also comprise red stone in the material of said crucible, the percentage composition＜30ppm of said red stone.
Further, can load the raw material of 400-450kg in the said crucible.
Compared with prior art, the utlity model has following advantage:
1, the crucible of the utility model is regular cubes hatch frame, is different from the single-wafer crucible, improves the output and the yield of silicon material greatly;
2, the crucible of the utility model is the geometric shape of rule, helps the thermal field uniform distribution, compound minimum melting's teacher thermograde;
3, the crucible volume size of the utility model is big, volume is big, ability disposable loading 400-450kg raw material, and the crystallization silicon ingot reaches 450kg, even bigger, consumes the about 2kw of electric energy;
4, the crucible of the utility model is compared with plumbago crucible and has been reduced the silicon ingot cutting output, removes the corner impurity of silicon ingot, and polycrystal silicon ingot is actual to use 6-7 times that is about silicon single crystal, has significantly improved economic benefit, is worth widespread use, promotes industry development and lifting.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technique means of understanding the utility model, and can implement according to the content of specification sheets, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 has provided the structural representation of an embodiment of the utility model.
Label declaration among the figure: 1, crucible.
Embodiment
Below with reference to accompanying drawing and combine embodiment, specify the utility model.
Referring to shown in Figure 1, a kind of crucible is characterized in that: the cube structure hatch frame of 1 one-tenth rule of said crucible.
Further, the material of said crucible is the high purity quartz material, the percentage composition of silicon-dioxide＞99.7% in the material composition of said crucible 1.
Further, also comprise aluminum oxide in the material of said crucible, said aluminum oxide percentage composition＜600ppm.
Further, also comprise red stone in the material of said crucible, the percentage composition＜30ppm of said red stone.
Further, can load the raw material of 400-450kg in the said crucible 1.。
The foregoing description is technical conceive and the characteristics for the utility model is described just, its objective is to be the content that lets the one of ordinary skilled in the art can understand the utility model and to implement according to this, can not limit the protection domain of the utility model with this.The variation or the modification of every equivalence of having done according to the essence of the utility model content all should be encompassed in the protection domain of the utility model.
Claims (3)
