The systematic name of this chemical is barium dioxidanediide. With the CAS registry number 1304-29-6, it is also named as Peroxyde de baryum. The product's categories are industrial / fine chemicals; inorganics; oxidation; peroxides; synthetic reagents. It is greyish white powder which is insoluble in water. In addition, it is noncombustible, but accelerates the burning of combustible material. Barium peroxide is one of the most common inorganic peroxides, and it is a peroxide, containing O₂^2- subunits wherein the oxygen atoms bond to each other as well as to the barium. Furthermore, it is not compatible with reducing agents, acids, bases, acetic anhydride, finely powdered metals, hydroxylamine, organic materials, and you must not take it combustible materials, heat and incompatible materials. This chemical should be sealed in the container and stored in the cool and dry place.

The other characteristics of this product can be summarized as: (1)ACD/LogP: -0.43; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -0.42; (4)ACD/LogD (pH 7.4): -0.42; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)#H bond acceptors: 2; (8)#H bond donors: 2; (9)#Freely Rotating Bonds: 1; (10)Enthalpy of Vaporization: 45.09 kJ/mol; (11)Boiling Point: 150.2 °C at 760 mmHg; (12)Vapour Pressure: 1.48 mmHg at 25°C.

Preparation of Barium peroxide: It can be obtained by the reversible absorption of O₂ by barium oxide. The oxygen is released above 500°C. 2 BaO + O₂ = 2 BaO₂

Uses of Barium peroxide: It is used for bleaching. And it is also used in fireworks as an oxidizer, which also gives a vivid green colour, as do all barium compounds.

When you are using this chemical, please be cautious about it as the following:
It may cause fire when contact with combustible material. And it is harmful by inhalation and if swallowed, so peopel should keep away from food, drink and animal foodstuffs. Additionally, it should kept away from combustible material.
