Copper Sulfide and Copper Sulphide are inorganic compounds. Copper Sulfide Chemical formula Is CuI2CuII(S2)S. Two-thirds (or more) of the sulfur is actually persulfate, and the remaining third is cuprous, which is extremely polar and dark brown. Because of its insoluble nature, it is second to silver sulfide or mercury sulfide as the most insoluble substance.

CuS Powder Copper Sulfide:

Copper1 sulfide an inorganic compound having the chemical formula CuS. It is either a cuprous sulfide or supersulfide mixture and is a black and granular amorphous material. This substance is very insoluble and can cause some strange reactions. The complex electronic structure of copper sulfide bonding cannot be accurately described by simple oxidation forms.

CuS Copper sulfideis both a compound or mineral. They can be classified into one, two, or three sulfides. Copper sulfide can be found in nature naturally as a mineral called cuprizone. It conducts electricity at a moderate level. It is present in both natural and synthetic materials.

Copper sulfide is a term that describes the combination of various minerals and compounds which are used to make synthetic materials and minerals. Some copper sulfides have economic importance. Cu2S, or copper porphyry, is the most important copper sulfide. The composition of copper sulfurides can vary greatly depending on where they are from. This includes non-stoichiometric compounds and 0.5 Cu/S 2.

How does Copper SulfideCuS Powder be made?

There is no way to heat copper and sulfur together in order to make copper sulfide. Because the sulfur oxidation is weak, it will result in a mixture between copper sulfide or cuprous sulfide.

2Cu+S==^==Cu2S , Cu+S==^==CuS

Copper powder can be made with sulfur.

Cu+S==100 , CS2==CuS

The laboratory preparation of copper sulfuride involves adding H2S gas (or soluble sulfide such as sodium sulfide), to copper salt (mostly copper chloride or copper sulfate), solution by double decomposition reaction.

CuCl2+H2S====CuS|+2HCl (weak acid to strong acid)

Because copper sulfide may be too insoluble, this can lead to an equilibrium shift to the right.
