What is Al2Se7? Important knowledge about Al2Se7.

Definition of Al₂Se₇
Al₂Se₇ is a chemical compound belonging to the oxide group, commonly known as Aluminium Selenide. It consists of two aluminum atoms and seven selenium atoms, with atomic masses of 26.98 and 78.96 respectively. The specific atomic mass of Al₂Se₇ is approximately 587.44. The molecular structure of Al₂Se₇ comprises two positive aluminum ions and seven negative selenium ions.

Properties: Al₂Se₇
Al₂Se₇ is a solid substance, with color ranging from white to gray. It has no distinct odor and is inactive in the process of diffusion. The chemical properties of Al₂Se₇ include its ability to react with water to produce selenium hydride, a toxic substance.

Common chemical equations of Al₂Se₇
Since Al₂Se₇ reacts with water to produce selenium hydride, it is not commonly used in chemical reactions with metals, acids, non-metals or salts.

Preparation of Al₂Se₇
Al₂Se₇ is not easily prepared in the laboratory due to the toxicity of selenium hydride, a byproduct of the reaction with water. In industry, Al₂Se₇ can be produced through the reaction of aluminum with selenium at high temperatures.
