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).
