What is CuSe? Important knowledge about CuSe.

Definition of CuSe
CuSe, also known as Copper Selenite, or Copper (I) Selenide in English, is a solid substance that can form black or dark blue crystals. CuSe consists of one copper (Cu) atom and one selenium (Se) atom. Its atomic weight is 142.48 uma. Its molecular structure is CuSe, in which the copper ion is the positive ion Cu+ and the selenite ion is the negative ion Se-.

Characteristics of CuSe
2.1 Physical properties of CuSe
CuSe is solid at room temperature. Its color is typically black or dark blue. CuSe does not have any distinct smell.
2.2 Chemical properties of CuSe
CuSe is a substance that is insoluble in water. It can react with strong acids to produce toxic gases such as organic selenium gas and selenium gas.

Common Chemical Reactions of CuSe
Since CuSe is insoluble in water, it rarely participates in reactions with metals, acids, non-metals, or salts. However, under high-temperature conditions, CuSe can react with oxygen to form CuO and SeO₂ gas.

Synthesis of CuSe
4.1 Laboratory synthesis of CuSe
CuSe is not typically synthesized in the laboratory due to the toxic properties of selenium.
4.2 Industrial synthesis of CuSe
In industry, CuSe is commonly synthesized from copper and selenium in a melting process.
