Description
[technical field]
The present invention relates to artificial lens field, specifically the present invention relates to a kind of tungsten cylinder to the volume regulation structure of quartz crucible.
[background technology]
Known, artificial lens is of a great variety, and the silicon single crystal wherein used in solar electrical energy generation, polysilicon play indispensable effect in field of solar thermal power generation; In work sheet crystal silicon, polysilicon, crucible usually can be used to carry out drawing or noting ingot, in the drawing of silicon single crystal, polysilicon or note ingot, quartz crucible is comparatively conventional; Crucible is used to carry out drawing or noting ingot, first the silicon single crystal of pulverizing or polysilicon fragment are put into crucible, then utilize in airtight furnace chamber and around the heating jacket of crucible outside, the silicon single crystal in crucible or polysilicon fragment are melted, inserted in the brilliant liquid melted by the seed crystal on drawing device and slowly promote, form lens cylinder, described lens cylinder is finished product crystal bar; Or utilize the airtight furnace chamber interior heating jacket around crucible outside the silicon single crystal in crucible or polysilicon fragment to be melted, when melting silicon single crystal or polysilicon fragment, make crucible bottom formation a little less than the low-temperature region on top by controlling heating jacket, the namely step temperature that is commonly called as of this area, by being arranged on the seed crystal that crucible bottom is not melted, make the brilliant liquid crystallization in reduction temperature crucible, form crystal ingot.
In said process, due to silicon single crystal in crucible or polysilicon fragment gap larger, make melt silicon single crystal or polycrystalline silicon wafer liquid measure less, if be processed into the crucible of the large degree of depth, the crucible standing worked crystal post or crystal ingot can only use several days and just can scrap, the mainly damage of crucible bottom, and top is but intact, cause serious waste, the brilliant liquid measure of the crucible silicon single crystal that the degree of depth is less or polycrystalline silicon wafer is less.
[summary of the invention]
In order to overcome the deficiency in background technology, the invention discloses a kind of tungsten cylinder to the volume regulation structure of quartz crucible, by adding the cylinder of tungsten or molybdenum materials matter on quartz crucible, utilize weather resistance and the high-temperature stability of tungsten or molybdenum, make the height reduction of quartz crucible, effectively reduce the usage quantity of quartz, significantly reduce use cost.
In order to realize the object of foregoing invention, the present invention adopts following technical scheme:
Tungsten cylinder, to a volume regulation structure for quartz crucible, comprises quartz crucible, tungsten or molybdenum cylinder, on the crucible of quartz crucible along be provided with around annular recess; Or the cavity top in quartz crucible is provided with extension diameter section, forms step between described extension diameter section and the lower cavity of quartz crucible; The lower end of tungsten or molybdenum cylinder is inserted in along in the annular recess arranged on crucible, and the lower end of described tungsten or molybdenum cylinder and annular recess are kissed and joined; Or the lower end of tungsten or molybdenum cylinder is inserted on the step of quartz crucible inner chamber body extension diameter section lower cavity, the lower end outer wall of tungsten or molybdenum cylinder and extension diameter section are kissed and are joined.
Described tungsten cylinder is to the volume regulation structure of quartz crucible, and the cavity wall in quartz crucible comprises on step and is provided with barium coating.
Described tungsten cylinder is to the volume regulation structure of quartz crucible, and described barium coat-thickness is 1 ~ 2mm.
By above-mentioned disclosure, the invention has the beneficial effects as follows:
Tungsten cylinder of the present invention is to the volume regulation structure of quartz crucible, by adding the cylinder of tungsten or molybdenum materials matter on quartz crucible, utilizing weather resistance and the high-temperature stability of tungsten or molybdenum, making the height reduction of quartz crucible, effectively reduce the usage quantity of quartz, significantly reduce use cost; Use cost of the present invention obtains and significantly reduces, and during thawing crystal, stability is higher; The material that crucible of the present invention uses is quartz sand, in view of mixing of quartz sand composition and silicon single crystal or polysilicon at high temperature easily appears in quartz sand, make to occur unnecessary composition in silicon single crystal or polysilicon, the barium coating that the present invention is arranged in quartz crucible can guarantee the quality of silicon single crystal.
