Zirconium Crucible

A zirconium crucible is a highly durable container used in different scientific and industrial applications, especially those involving high-temperature processes. Zirconium, a chemical element with the symbol Zr and atomic number 40, is preferred for manufacturing crucibles due to its high melting point, excellent corrosion resistance, and substantial heat and wear resistance.

Zirconium Crucible Properties

High Melting Point: The melting point at 1852℃, which makes it suitable for melting and casting metals with high melting points like platinum, titanium, and superalloys.
Corrosion Resistance: Corrosion resistance to various acids, alkalis, and molten metals is ideal for handling aggressive substances and preserving purity during high-temperature processes.
Low Thermal Expansion: It minimizes dimensional changes with temperature fluctuations, reducing the risk of cracking or warping.
Chemical Inertness: Zirconium is relatively inert and does not readily react with most molten metals or other materials, preserving the purity of the processed materials.

Dimension of a Zirconium Crucible

Outside Diameter: 10 – 700mm
Height: 25 – 900mm
wall thickness: 3 – 30mm.
Volume capacity: varies from a few milliliters for laboratory use to several liters for industrial applications.

Applications

Melting and Casting Reactive Metals: This includes titanium, zirconium, and their alloys, as well as platinum and other precious metals.
Investment Casting Processes: to create high-precision complex metal components.
Fusion fluxes: They are used to prepare for analytical chemistry and materials science research.
Crystal Growth Processes: These are used to grow high-purity crystals of various materials.
Nuclear Fuel Processing: Zirconium’s low neutron absorption cross-section makes it suitable for specialized crucibles in nuclear fuel processing.
