A pure nickel crucible is a container or vessel used in high-temperature processes, made from high-purity nickel.

1. Properties of pure nickel

High-temperature resistance: Nickel has a melting point of 1453°C. Pure nickel crucibles can operate stably for extended periods at temperatures below 1200°C and can withstand higher temperatures for short periods.

Excellent antioxidant properties: At high temperatures, a dense nickel oxide (NiO) layer forms on the surface, slowing down further oxidation.

Corrosion resistance: Resistant to alkaline media and corrosion by certain molten salts.

Mechanical Properties: Retains high strength even at high temperatures and is resistant to deformation.

4. Application Fields

Porous carbon materials: Pure nickel has a high melting point and is well-suited for the high-temperature carbonization of porous carbons, particularly providing a stable environment during chemical activation or template-assisted carbonization. Nickel (Ni) can serve as a catalyst for the cracking of carbon sources such as methane and ethylene, promoting graphitization or the growth of carbon nanotubes and thereby enabling precise control over the conductivity and pore structure of porous carbons.

Single-crystal growth: a melting or annealing process used for certain oxide crystals.

Thermal treatment of battery materials: such as calcination of lithium-ion cathode materials (e.g., nickel-cobalt-manganese compounds).

Laboratory research: Synthesis or testing of materials under high-purity conditions.
