Q: Do you support customization of special specifications in addition to regular sizes? A: Yes, we provide professional customization services. We can accurately customize parameters such as capacity (10ml to 1000ml and above), caliber size, height, wall thickness, etc. according to your specific process requirements. Q: Can transparent quartz crucibles come into contact with hydrofluoric acid or strong alkali? A: The main component of quartz is silicon dioxide, which has excellent corrosion resistance to ordinary dilute inorganic acids, except for hydrofluoric acid. But at high temperatures, it is highly prone to react with caustic soda and alkali metal carbonates, so it is not recommended to use it in such environments. Q: What is the difference between fully transparent structure and semi transparent structure, and how to choose? A: The fully transparent crucible has extremely high light transmittance, making it convenient for real-time optical monitoring during the experimental process; The semi transparent (or bubble layer) structure can provide more uniform thermal radiation conditions in industrial crystal pulling. We will recommend the most suitable material structure for you based on your specific application scenario.
