Nickel is completely resistant to phosphoric acid, as well as being highly resistant to the corrosive effects of the strongest alkalis. The metal is also resistant to dry hydrogen chloride, hydrogen fluoride and chlorine up to about 535°C.
In addition to their low cost, nickel crucibles can even replace platinum in fusions where zirconium cannot be used.
For instance; sodium peroxide fusions where zirconium itself is to be determined; also in analysis for columbiums (niobium), tantalum, or low phosphorus.
Although significant amounts of nickel can be introduced into samples, it can be removed easily by several ammonia separations.
Life expectancy of a nickel crucible is from 4 to 6 fusions. They present an advantage, other than cost, if small amounts of zirconium are present, or if its removal with Mandelic Acid is unsatisfactory.
If small amounts of phosphorous are to be determined because of extremely low solubility of zirconium phosphate, then nickel must be used.
Standard thickness for Low Form and Straight Wall: 0.035”; High Form: 0.021” (20 to 150ml) and 0.035” (250 to 500ml).
