Stability Unstable - may decompose spontaneously and violently to oxygen. Mixtures containing a moderate partial pressure of ozone, and pure ozone at even low pressures are both potentially explosive. May react very violently with combustible materials and reducing agents, such as organics. Even small quantities of organic material, such as traces of g
