Zirconium Crucibles Information - Facts and Advantages

The remarkable corrosion resistant qualities of Zirconium are used extensively in the Chemical Processing Industry. Zirconium will withstand a wider range of caustics and acids to a greater degree than any other commonly used fabricating material.

Zirconium Crucibles

It is no secret that zirconium crucibles cost more than porcelain, steel or nickel. Quite a bit more. But, based on an average number of fusions which can be made in a zirconium crucible, as opposed to those of nickel, the ratio of longevity stands at 20 to 1. Therefore, the higher cost of zirconium crucibles is recovered three times over. In addition to cost effectiveness, zirconium crucibles hold several advantages over other materials.

If compared to platinum crucibles, several distinct advantages are readily apparent.

1. Improper procedure in heating over a Bunsen burner can cause the reducible contents to be converted into harmful, low-fusing metals which may react with the platinum crucibles.

2. No platinum tipped tongs or special triangles are required for handling hot zirconium crucibles.

3. Sudden contact with cold, metallic surfaces will have no deleterious effects on a zirconium crucible.

4. Hydrofluoric acid is the only cleaning agent which should not be used to clean zirconium crucibles.

5. Smoothing and shaping after use is not a special consideration. Zirconium crucibles require a minimum of specialized care.

6. The inherent strength of zirconium precludes the necessity of reinforced rims and thicker bottoms as is the case of platinum crucibles in certain instances.

Zirconium crucibles are especially adaptable to the needs of the analytical chemistry laboratory, such as in strong alkaline fusions employed to reduce refractory samples to a soluble form, and for high temperature ignition ashing purposes.
Zirconium metal is a most effective all-round crucible for fusions using sodium carbonate or sodium peroxide and is an excellent low-cost replacement for platinum crucibles. Based on an average of 100 fusions per crucible, zirconium is more cost-effective than less expensive crucibles of porcelain

or steel.
