Shanghai Metal Corporation is a leading nickel crucibles manufacturer and supplier.
Nickel has strong resistance to alkalinity and corrosion, so nickel crucibles are commonly used for melting iron alloys, slag, clay, refractory materials, etc. Nickel crucibles are suitable for melting samples with NaOH, Na2O2, NaCO3, and alkaline fluxes containing KNO3. Samples cannot be melted with KHSO4, NaHSO4, K2S2O7, or Na2S2O7, as well as alkaline sulfide fluxes containing sulfur. The melting point of nickel is 1455 degrees Celsius, and the temperature of melting the sample in a nickel crucible should not exceed 700 ℃, as nickel is prone to oxidation at high temperatures. Nickel crucibles often contain trace amounts of chromium, and attention should be paid when using them. The new nickel crucible should be first burned in a muffle furnace to a blue purple color to remove surface oil stains, then boiled with 1:20 (volume ratio) hydrochloric acid for a moment, and then rinsed clean with water. Molten metal salts such as Al, Zn, Pb, Sn, Hg, etc. can make nickel crucibles brittle. Nickel crucibles cannot be used for calcination of precipitates. Borax cannot be melted in a nickel crucible.
