  • Description + -

    Zirconium exhibits excellent resistance to corrosion in most organic and inorganic solutions.

    Zirconium is our most effective crucible material for fusions using sodium carbonate or sodium peroxide. It is an excellent low-cost replacement for platinum. And, based on an average of 100 fusions per crucible, it is more cost effective than less expensive porcelain or steel crucibles.

  • Product Details + -

    The major use of zirconium remains in the nuclear reactor arena. The thermal neutron capture cross-section is extremely low so the metal acts as a window to these particles. It also exhibits good corrosion resistance to the aqueous media within the operational nuclear reactor.

    Other advantages of zirconium are its complete resistance to the action of most solvents of all concentrations such as nitric, hydrochloric, sulfuric and perchloric acids. This allows the fusions to be dissolved out of the crucible completely with little or no contamination of the sample. Alkaline solvents such as ammonium hydroxide, acetate sulfi de, carbonate and (Na, K) hydroxide, sulfide, carbonate and cyanide are also without effect.

    Zirconium exhibits superb corrosion resistance in most organic and inorganic
    acids, salt solutions, strong alkalis and a few molten salts. The passive oxide film
    (corrosion barrier) is stable in both reducing and oxidizing conditions. Zirconium is
    excellent in both acid and base solutions. The temperature limit for use in air is
    about 450˚C to 500˚C.
