Nickel (II) sulfide particles are the granular form of nickel (II) sulfide.
Basic information:
Appearance: Usually black powder particles, the color is more uniform.
Density: Has a relatively high density.
Melting point: The melting point is relatively high, about 797 ° C, which makes NiS particles can still maintain good stability in high temperature environment, and can be applied to some high temperature reactions or areas requiring high temperature resistance of materials.
Crystal structure: NiS has a variety of crystal structures, the common hexagonal crystal system.
Preparation method:
Direct synthesis method: The reaction of nickel salt (such as nickel chloride, nickel sulfate, etc.) solution with hydrogen sulfide gas can prepare Nickel (II) sulfide particles.
High temperature solid phase method: the nickel powder and sulfur powder are mixed in a certain proportion, and the solid phase reaction is carried out at high temperature, which can also prepare NiS particles.
Catalyst: In some chemical reactions, NiS particles can be used as a catalyst, such as in the process of hydrogenation reaction, desulfurization reaction, etc., to accelerate the reaction and improve the efficiency of the reaction.
Battery materials: Due to their unique chemical properties and electronic structure, NiS particles have potential applications in the field of batteries, which can be used as electrode materials in energy storage devices such as lithium-ion batteries and supercapacitors.
