Zirconium Crucible Description
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 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'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.
