Notes:

1. The melting point of Nickel is 1455. Nickel have strong alkali resistance and anti-corrision. So the nickel crucible usually is used to melt Fe alloy, slag, clay, fire resistance material.

2. The melting temp of Nickel crucible can not surpass 700, Under high temperature, the nickel is easy to be oxidized.

3. Nickel crucible can not be used for the ignition of the precipitate.

4. Nickel crucible is suitable to melt NaOH Na2O2,Na2CO3 NaHCO3 etc but not suitable KHSO, NaHS04, K2S2O, Na2S2O7.

5. The metal such as Al,Zn, Pb,Sn,Hg, all can make nickel crucible very fragile. Borax also can not be melted in nickel crucible.

6. Nickel crucible containing traces of chromium, we should pay attention to it when using
