Our company supply 25ml 30 ml 50 ml 100 ml nickel crucible
1. Melting point is 1455 degrees of nickel, nickel, strong alkali resistance and erosion resistance of nickel substitutes crucible melting iron alloy, slag, clay, fire-proof material, etc.
2. In nickel sample crucible melting temperature should not be more than 700 degrees, because in the high temperature, nickel susceptible to oxidation.
3, nickel precipitation crucible cannot be used for the burn.
4, nickel crucible is suitable for 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. Molten state of Al, zinc, Pb, Sn, Hg and other metal salt, can make the nickel crucible brittle.Borax in nickel crucible melting.
6. Trace chromium, nickel crucible often contains should be paid attention to while using it.
7, new nickel should look in the muffle furnace crucible burn into violet, removal of surface oil, then use 1: HCl boil for a minute, then rinse clean with water.
