    Barium Oxide: Properties, Processing, and Applications

    Production and processing of barium oxide. Barium oxide can be produced by thermally decomposing barium carbonate, BaCO 3 or barium nitrate, Ba(NO 3) 2. The reactions are as follows: BaCO 3 → BaO + CO 2. 2Ba(NO 3) 2 → 2BaO + 4NO 2 + O 2. It can also be produced by the reaction of pure barium with oxygen as shown below. 2Ba + O 2 → 2BaO

    Barium Oxide: Properties, Processing, and Applications

    Barium Oxide: Properties, Processing, and Applications. Barium is found in ores, mostly in the form of barite (BaSO4) as it does not occur naturally as a free element. Barium makes up 0.05% of the earth’s crust. It is a member of the alkaline earth metals and it has a pale yellow and shiny appearance. Barium was discovered in 1772 by Carl

    Merete Tangstad, in Handbook of Ferroalloys, 2013. 7.5.1 Basics of Reduction Processes. Manganese ores will always contain some iron oxides. Reduction of the iron oxides in the ore is probably almost complete when the temperature reaches 1200°C. The product will be a carbon-saturated iron alloy with an increasing content of manganese at increasing reductions in temperature.

    Barium oxide (BaO) forms during the dissociation of barium carbonate (BaCO 3) at 700° to 900°C. Barium carbonate (77.69% BaO), like strontium carbonate, exists in three modifications: up to 840°C α-BaCO 3 with orthorhombic lattice (a = 0.639 nm, b = 0.883 nm, c = 0.528 nm); in the range 840° to 960°C, β-phase with a hexagonal lattice; and 982°C, γ-BaCO 3 with a cubic lattice.
