Impurities in the container could react with the molten silicon, so you need an equally pure quartz crucible to hold it. Most chip makers and their suppliers have enough silicon wafers or silicon ...

Researchers from Norway and Germany investigated the influence of impurities in fused quartz crucibles used in silicon PV ingot production. The results suggest that the key factors influencing ...

The quartz found at Spruce Pine is used in crucibles to melt down polysilicon to make the base of semiconductors because it can withstand the heat needed to melt the polysilicon and has a molecular ...

Quartz’s ability to withstand extreme temperatures is useful for making crucibles or containers that hold the melted ...

High purity quartz is used in the semiconductor industry to produce crucibles and quartz glass products such as windows, rods, and tubes. High purity quartz is also used in the production of silicon ...
