Zirconia Crucibles Engineered for Increased Foundry Productivity at Temperatures up to 1900°C and Beyond
Zirconium Oxide Crucibles deliver cleaner melts at temperatures up to 1900°C and beyond. They are engineered for the melting of superalloys and precious metals and deliver heat-up and cool-down schedules that keep your foundry productive. For immediate delivery, we inventory the most common crucible sizes, with configurations to suit your particular needs. Markets served include: Aerospace, Power Generation, Medical, Precious Metals and Dental.
For Even Longer Crucible Life
Zirconium Oxide (ZrO2, A Grain Zirconia) is one of the best commercially available insulating materials. It has approximately 5 times the insulating value of alumina or magnesia. Using 1859 or 3001 Crucible Backup will extend crucible life and result in cleaner melts(www.zircoa.com/grog).
Calculate Zirconia Crucible Capacity
Our online calculator can help you determine which Zircoa zirconia crucible is right for your particular application. For your convenience, the calculator includes an extensive list of alloys and numerous user definable fields. Microsoft Excel required( www.zircoa.com/crucible.calculator).
