Zirconium Crucible

As a leading supplier of Zirconium products across the world, Edgetech offers customers high-quality Zirconium Crucibles at a very competitive price. Customized forms are also available upon your request.

Zirconium Crucibles are ideal for melting other metals because zirconium has better mechanical strength at high temperatures than most other metals. Compared with Nickel Crucibles, Zirconium Crucibles cost more but have better cost-effectiveness as the number of fusions that can be made in a Zirconium Crucible is much higher than other metals. Zirconium Crucible requires minimum care and won& #39;t act as a catalyst for oxidation and reaction, unlike platinum. The corrosion resistance of Zirconium comes from a tightly adhered oxide, zirconia, which forms almost instantaneously. As a result, Zirconium Crucibles resist the corrosion of almost all acids, except hydrofluoric acid. Thus, HF is the only cleaning agent that should not be applied to Zirconium Crucibles.

Zirconium (Zr) is a kind of silver metal with a density of 6.52 g/cm3. Zr has a very small neutron absorption cross-section and a relatively high melting point (1855 °C or 3371 °F), making zirconium a great material for nuclear power rods. In the 1990s, about 90% of Zirconium produced every year is consumed by the nuclear industry. However, as more and more people get familiar with Zr and its compound, more applications have been found. Zirconium metal and Zirconium alloys have advantages in specialized chemical processes-primarily acetic and hydrochloric acids.

Zirconium Crucible Applications
-Aerospace industry: used to manufacture aircraft structural parts, engine parts and spacecraft parts, using its excellent strength-to-weight ratio to reduce aircraft weight and improve fuel efficiency and performance.
-Chemical industry: used to manufacture corrosion-resistant chemical equipment such as reactors, containers and pipelines.
Due to its excellent corrosion resistance, it can withstand erosion by a variety of corrosive media.
-Marine engineering: used to manufacture offshore platforms, ship parts, seawater desalination equipment, etc., due to its good resistance to seawater corrosion, it can be used for a long time in the marine environment.
-Medical devices: used to manufacture medical implants such as artificial joints, dental implants, etc., due to its good biocompatibility, it is not easy to cause human rejection.
-Automobile industry: used to manufacture automobile exhaust systems, chassis parts and body structures, using its light weight and high strength characteristics to improve automobile performance and fuel efficiency.
