Inert and gases
Inert atmospheres consisting of gases such as argon, nitrogen, or helium are commonly used in chemical reaction chambers and in storage containers for air-sensitive or water-sensitive substances, to prevent unwanted side-reactions of these substances with air and water.
Inert gases ( most often carbon dioxide and water ) produced by thermal degradation of some materials act as diluents of the combustible gases, lowering their partial pressures and the partial pressure of oxygen, and slowing the reaction rate.
