High purity 99.96% 100ml Nickel Crucible for laboratory
1.The melting point of nickel is 1455 degrees, and the nickel is anti-erosion and alkali resistance , so nickel crucible is used to melt ferroalloy, slag, clay and refractory materials.
2.The melting temperature of nickel crucible should not exceed 700 degrees, because nickel is easily oxidized at high temperature.
3. The nickel crucible cannot be used to precipitate the burning.
4. Nickel crucible is suitable for the NaOH Na2O2, Na2CO3 NaHCO3 and contains samples of alkaline solvent melting - KNO3, does not apply to e-isomer NaHS04, K2S2O7 or Na2S2O7 acidity such as solvent and sour alkali sulphide flux melting sample.
5.The melting state of A1, Zn, Pb, Sn, Hg and other metal salts can make the nickel crucible brittle.Borax does not melt in a nickel crucible.
6.Nickel crucible often contains trace chromium, which should be noted when used.
7. The new nickel crucible should be burned into a blue violet in the muffle furnace, remove the oil from the surface, then boil for a moment with 1:20 HCl, then rinse off with water.

Description
Laboratory Nickel Crucible, nickel 201 spec (minimum 99.6% nickel content), formed to shape from one nickel billet, bright finish inside and out. Supplied in standard packs of 10.
Heating/Cooling Information
Working temperature range up to 350°C will ensure crucible has a long working life.
Temperature range 350°C - 600°C will shorten the working life of the crucible due to oxidisation.
Temperature range 600°C - 800°C will show increased levels of oxidisation on the crucible and dramatically reduce its life.
Temperature range 800°C + will lead to severe oxidisation and render the crucible unusable.
The thicker the crucible wall the longer it lasts at elevated temperatures resisting oxidation process and can extend its life.
Features and Benefits
Why Nickel crucibles?
Nickel forms a tightly adhering oxide file between 400°C and 600°C in oxidizing atmospheres.
In choosing crucibles for laboratory work, nickel can be effective with regard to cost per crucible, and for use in fusions where zirconium or other metals cannot be used.
It is even a cost-effective replacement for platinum in those applications for which zirconium must not be used.
In the analytical laboratory, nickel crucibles provide a low cost crucible.
