Zirconium Crucible, Zr Crucible

Zirconium Crucible, Zr Crucible

Zirconium crucibles, also known as Zr crucibles, are containers made from zirconium metal that are used to hold and melt materials at high temperatures in various applications. Zirconium is a refractory metal with a high melting point and excellent resistance to corrosion and chemical attack, making it an ideal material for use in high-temperature applications.

Zirconium crucibles are commonly used in the production of specialty alloys, superalloys, and semiconductors. They are also used in laboratory research for the preparation of samples and the growth of crystals. Zirconium crucibles are known for their high resistance to oxidation, which makes them an ideal choice for melting materials in air or oxygen-rich environments.

Zirconium crucibles are typically made by a powder metallurgy process, where zirconium powder is pressed and sintered to form the crucible shape. They are available in a range of sizes and shapes to meet specific application requirements. Zirconium crucibles are also commonly used in combination with other materials such as graphite or alumina to improve their properties or reduce cost.
