These crucibles are manufactured from nickel. Available in high form, low form and straight wall types.

• Resistant to phosphoric acid
• Highly resistant to the corrosive effect of the strongest alkalies

Nickel crucibles offer high resistance to dilute alkalies. In some instances, nickel crucibles are preferable to zirconium: for instance, sodium peroxide fusions in which zirconium itself is to be determined; also in analysis for columbium (niobium), tantalum or low phosphorus.
