Zirconia Crucible (ZrO2 Crucible)

Edgetech Industries, Advanced Ceramics Division supplies high-quality and competitive price advanced Zirconia (ZrO2) Crucible.


Zirconia Crucible, ZrO2 Ceramic Crucible, Yttria Stabilized Zirconia Crucibles


Zirconia (ZrO2) crucibles are great refractory and insulating containers. They have a clean melt at temperatures above 1900°C and above and are specially manufactured for melting superalloys and precious metals. They also have excellent chemical inertness, superior thermal shock resistance to temperatures reaching up to 2200°C, and good corrosion resistance to acids and alkalis. The material for the Zirconia crucible will be Yttrium oxide fully stabilized zirconia (8mol-YSZ), while partially stabilized zirconia ceramics are mostly used for corrosion and wear resistant products.

Zirconia Crucible Types:


Our zirconia crucible’s temperature resistance is around 2000 ℃, two types of them are divided as follows:

Refractory grade zirconia crucible, Density: 4.5g/cc, has micropores inside, also named a semi-ceramic crucible. It exhibits corrosion resistance performance of zirconia, is stable in the oxidizing and reducing atmosphere, and it is very resistant to many solutions and slag. At the same time, it has the thermal shock resistance of refractory materials, which greatly improves the change of temperature gradient during use, and is widely used in the smelting of platinum and other rare precious metals. Three main size of this type: 250ml, 5.0mmOD x 8.0mm H, 6.8mmOD x 4.0mm H. The last one is used as a thermal analysis crucible; it solves the analysis for materials that will react with alumina crucible at a high temperature

Ceramic grade zirconia crucible, density: 6.0g/cc, fully densified, and no pores. High-purity ceramic zirconia crucible is white, it will show yellow or grey if the purity is lower. It has stable chemical properties, except for sulfuric acid and hydrogen sulfuric acid, it has good stability to other acids, alkalis and alkali melts, glass melts and molten metals, low thermal conductivity, good thermal stability, and high temperature creep. The thermal conductivity is low, and the coefficient of thermal expansion is close to that of metal materials. It is an important structural ceramic material.


Zirconia Crucible Applications


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. They are widely used in:

-Chemical calcining

-Metal casting

-Metal melting, especially in superalloy and precious metals industries

-Thermal analysis crucibles
