Description of Zirconium Crucible

Zirconium (Zr) crucibles are made from zirconium, a highly resistant, strong, silver-gray transition metal with a melting point of 1,855°C and outstanding corrosion resistance. These characteristics make them well-suited for high-temperature environments, particularly in labs and industrial processes that demand materials capable of withstanding extreme heat and aggressive chemicals. Zirconium crucibles can be produced through forging or welding methods. Seamless zirconium crucibles, recognized for their exceptional strength, thermal durability, and corrosion resistance, are ideal for challenging high-temperature applications.

Zr Crucible Features and Application

Chemical Processing: Used in handling aggressive chemicals and corrosive agents at elevated temperatures.

Metal Casting: Ideal for melting and casting reactive metals and alloys like titanium and hafnium.

Nuclear Industry: Due to zirconium’s low neutron absorption, it is often used in nuclear reactors and related applications.

Aerospace and Defense: Suitable for use in extreme conditions, including high-heat aerospace and defense systems.

Essential factors for selecting the right Zirconium crucible

High purity Zirconium Zr Crucible Seamless Crucible

Purity Level

Verify the purity level of the Zirconium material used in the crucible, particularly for specialized applications like electronics.

Size and Capacity

Confirm the size and capacity requirements for your application

Material Compatibility

Ensure that the material does not chemically react with Zirconium and confirm that Zirconium itself meets the physical properties required for the working conditions, such as melting point and reactivity with the environmental atmosphere.

Customized Requirements

Provide detailed customization requirements, including drawings, working conditions, and product application information.
