Abstract
The utility model discloses a coating quartz crucible for producing solar silicon single-crystal, comprising a quartz crucible body, wherein the internal wall of the quartz crucible body is provided with a layer of barium carbonate coating. In the utility model, the service life of the quartz crucible can be drastically prolonged, and the finished-product rate of the long crystal can be effectively improved. Furthermore, a layer of fine-grained quartzite crystal is formed on the internal wall of the quartz crucible, thus increasing the strength of the quartz crucible and reducing the phenomenon of high-temperature softening.
Description
Technical field
The utility model relates to a kind of solar power silicon production quartz crucible, specifically a kind of solar energy silicon single crystal production coating quartz crucible.
Background technology
Quartz crucible is that one of element is wanted in the life that solar energy silicon single crystal is produced, and it not only influences long brilliant yield rate, also can influence the electric property of monocrystalline.Solar energy silicon single crystal production is that blocky high-purity polycrystalline silicon is placed quartz crucible, and heating makes its fusing, and the seed crystal that utilizes silicon single-crystal the to make seeding of sowing, and reaches the purpose of getting rid of dislocation, thereby draws out dislocation-free single crystal.Because chemical reaction can take place in molten silicon melt and quartz crucible under hot environment, inner wall of quartz crucible is produced corrode, not only reduced the resistant to elevated temperatures ability of quartz crucible, also influenced the purity of silicon single-crystal simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the prior art deficiency, and a kind of solar energy silicon single crystal production coating quartz crucible is provided.
The technical solution adopted in the utility model: a kind of solar energy silicon single crystal production coating quartz crucible, comprise quartz crucible crucible body, the inwall of described quartz crucible crucible body is provided with one deck barium carbonate coating.
The utility model is coated with the hydrated barta layer that thickness contains crystal water uniformly at the inner wall of quartz crucible of solar energy silicon single crystal production usefulness, and hydrated barta coating and carbon dioxide in air reaction can generate barium carbonate.When this coating quartz crucible is heated on single crystal growing furnace, barium carbonate will be decomposed to form barium oxide, and barium oxide can form silicon acid barium (BaSiO with the quartz crucible reaction again
3).Because the existence of silicon acid barium, make to form the fine and close small cristobalite crystallization of one deck on the quartz crucible wall that this small cristobalite crystallization is difficult to be infiltrated by solution and peel off, and is dissolved by solution even peel off also very fast meeting.
Beneficial effect; The utility model can prolong the work-ing life of quartz crucible significantly, can effectively improve long brilliant yield rate.One deck cristobalite crystallization that forms on inner wall of quartz crucible in addition can increase the intensity of quartz crucible, reduces the phenomenon of hot mastication.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with embodiment:
As shown in drawings: a kind of solar energy silicon single crystal production coating quartz crucible, comprise quartz crucible crucible body 1, the inwall of described quartz crucible crucible body 1 is provided with one deck barium carbonate coating 2.
Claims (1)
1. a solar energy silicon single crystal production coating quartz crucible comprises quartz crucible crucible body (1), it is characterized in that: the inwall of described quartz crucible crucible body (1) is provided with one deck barium carbonate coating (2).
