Description
Technical field
It can be used to observe air bubble content and the device of size in transparency silica glass crucible the present invention relates to a kind of, be applied to
Crystal growth can be used for the vacuum transparent layer of observation silica crucible with translucent silica crucible field, this device.
Background technology
Quartz glass crucibles load container as silicon material, are the important auxiliaries in silicon single crystal rod production, in photovoltaic and partly lead
Bulk single crystal si industry has substantial amounts of application.The quality of quartz glass crucibles directly influences monocrystalline silicon quality, and then has influence on
The performance of final products solar cell and semiconductor devices.In recent years, the dog-eat-dog of solar photovoltaic industry, silicon single crystal rod
Manufacturing enterprise is also constantly reducing into original holding enterprise competitiveness, such as takes single stove persistently to feed many silicon rods of drawing to improve
The measures such as efficiency.Therefore quartz glass crucibles also need higher quality to meet the requirement of monocrystalline silicon production enterprise.Hyaline layer
Bubble improvement is silica crucible manufacturing enterprise in an important directions being continually striving to.According to disclosed known technology, quartz
The manufacturing process of glass pot typically uses vacuum arc Process.Utilize based on centrifugal forming, using moulding stick, make stone
Sand powder is preforming in the graphite jig cavity for vacuumizing stomata（Graphite jig is inserted in metal water-cooling set）, and
Start to vacuumize.Then by the graphite electrode starting the arc and insert in molded quartz sand powder cavity, by high-temperature electric arc to base
Body carries out calcination, makes its rapid melting into the vitreous silica of crucible shape.Wherein stop vacuumizing after melting starts 3 ~ 5min.
After quartz glass crucibles cooling after take out, that is, complete a blank production, then it is cleaved it is clean wait handle after carry out inner surface
Spraying forms coating, and then completes the making of a quartz glass crucibles finished product.
The vacuum transparent layer of silica crucible is initially formed after the starting the arc, and required thickness is reached after 3 ~ 5min.Vacuum transparent layer
In forming process, due to there is the reasons such as gap, evacuation process design and impurity pollution between quartz sand particle, it can produce
Some raw bubbles.Wherein larger bubble, visually can distinguish and judge；The microbubble that some minimum naked eyes difficulties are shown in（Typically
Below 0.5mm）, just can not observe and distinguish.But these micro-bubble majorities are enriched in 0 ~ 500um below hyaline layer top layer
Area, during quartz glass crucibles long-time crystal pulling use, constantly expansion can become big, or even be spilled over to inner surface of crucible,
Molten silicon corrodes lower rupture, and the gaseous impurity of the interior parcel of bubble, which can dissolve in, may influence silicon rod quality in silicon liquid.If a large amount of small
Bubble ruptures in quartz crucible surface, can also destroy the barium crystallizing layer of coating.The barium silicate crystallizing layer of quartz crucible surface is played
The molten silicon of barrier protects the effect of silica crucible, and table in silica crucible is likely to result in after being destroyed and produces the bad of Pinhole-shaped siliconising
Phenomenon, also results in coating shedding when serious, can have a strong impact on single crystal growth process, reduces yield rate.Therefore, a kind of see is developed
The bubble density of crucible hyaline layer is surveyed, the method and apparatus of top layer microbubble density are anticipated to management and control and improvement silica crucible quality
Justice is great.
