Description

一种大尺寸石英陶瓷坩埚
技术领域
本实用新型涉及坩埚技术领域,尤其是涉及一种大尺寸石英陶瓷坩埚。 
背景技术
石英陶瓷坩埚在用于多晶硅熔炼铸锭使用时,由于其使用条件极其苛刻,对坩埚的纯度、强度、外观缺陷、内在质量、高温性能、热振稳定性、尺寸精度等都有极其严格的要求。目前,国内尚无对600L×600B×400H~900L×900B×500Hmm、壁厚15-20mm大尺寸石英陶瓷坩埚的研制和生产厂家。 
此种石英陶瓷坩埚存在的重要缺陷,由于该种规格的高度在400~500mm、壁厚在15-20mm之间,在应用多晶硅熔炼铸锭时,壁厚>2mm时,将会延长铸锭时间2小时,而高度增加后,同样会延长铸锭时间;同时,石英陶瓷坩埚纯度sio2>99.95%,极易导致石英陶瓷坩埚内所含杂质以及铸锭液内的杂质不断释放出来,造成铸锭损失 
实用新型内容
为克服上述问题,解决坩埚熔炼铸锭时间长、坩埚壁较厚导致铸锭时间延长的问题,本实用新型采用的技术方案如下: 
一种大尺寸石英陶瓷坩埚,包括坩埚,所述坩埚底部外部和内部四个角设有圆倒角,坩埚两两相交的面为圆弧过渡面。 
所述坩埚呈正方形。 
坩埚壁厚为5-8mm。 
本实用新型的优点:坩埚壁比较薄,强度大缩短铸锭时间。 
附图说明
图1是本实用新型的结构示意图。 
具体实施方式
如图1所示,一种大尺寸石英陶瓷坩埚,包括坩埚2,所述坩埚2底部外部和内部四个角设有圆倒角3,坩埚2两两相交的面为圆弧过渡面4。 
所述坩埚2呈方形。 
坩埚壁1厚为5-8mm。 
以上所述,仅为本实用新型的具体实施方式,但本实用新型的保护范围并不局限于此,任何熟悉本领域的技术人员在本实用新型所揭露的技术范围内,可轻易想到的变化或替换,都应涵盖在本实用新型的保护范围之内。因此,本实用新型的保护范围应该以权利要求书所限定的保护范围为准。
