❓ Frequently Asked Questions
Q
What grade of zirconium is used in your crucibles, and what does it mean?
Our crucibles are manufactured using R60702 grade zirconium alloy, which is an unalloyed commercial-purity zirconium. This grade requires a total Zr+Hf content of ≥ 99.2%, ensuring exceptional chemical purity, outstanding corrosion resistance, and reliable performance in high-temperature industrial applications.
Q
Can I order a zirconium crucible with custom dimensions or a special shape?
Yes. We offer fully customized processing services, including custom dimensions, special-shaped crucibles (beyond standard cylindrical and square forms), welding lug handles, and precision drilling. Please contact us with your specific requirements and we will provide a tailored solution.
Q
What surface finishes are available for the zirconium crucible?
We offer three surface finish options: Pickled Surface (clean, oxide-free finish achieved through acid treatment), Polished Surface (smooth, bright finish for applications requiring low contamination), and As-Forged Surface (natural surface after forging, suitable for general industrial use).
Q
What manufacturing processes are used to produce the zirconium crucibles?
Our zirconium crucibles are produced using advanced forming methods including Stamping Forming, Spinning Forming, and Welding Forming, all followed by a Vacuum Annealing process. Vacuum annealing relieves internal stress and restores optimal material properties, ensuring dimensional stability and long service life.
Q
What is the minimum order quantity, and are bulk discounts available?
The minimum order quantity is 1 piece, making it easy to sample or fulfill small-scale needs. For larger orders, discounts are available and pricing is calculated based on actual order volume. Please reach out to our sales team for a bulk purchase quotation.
Q
In which industries or applications are zirconium crucibles commonly used?
Zirconium crucibles are widely used in industries that require high-temperature melting, chemical processing, and laboratory analysis. Typical applications include melting reactive metals and alloys, chemical synthesis involving strong acids or alkalis, nuclear material processing, ceramic sintering, and precision casting — thanks to zirconium's superior corrosion resistance and thermal stability.
