About Mohammed Saif Zaveri →Quartz Crucibles & Quartzware: FAQs
Which crucible sizes do you supply?
22 to 36 inch crucibles for solar and semiconductor CZ pullers, confirmed against your hot zone and charge weight.
Why does crucible quality matter?
The crucible is in contact with molten silicon for the whole pull. Bubble content, inner-layer quality and purity affect oxygen in the ingot, crucible life and how many ingots you get per run.
Do you test quartz?
Yes. JRST runs quartz testing (ICP impurity analysis, bubble and fluid-inclusion checks, OH content, melt tests) through its quartz programme.
