Features

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
