Barium protoxide

Barium Oxide (Barium Monoxide, Baryta, Barium Protoxide, Calcined Baryta). BaO, mw 153.36 colorl or white to yelsh-white deliq powd mp 1923°, bp 2000°, d 5.72g/cc. Sol in dil acids, ethanol, methanol and w (decomps with a large amt of heat being evolved). Prepn is by thermal decompn of BaCOj under high vacuum. It is a product of the burning of the many barium compds present in pyrots and, as discussed above, it is used as an anti-barrel wear additive in proplnt compns...

Barex The trade name for BP Chemical International s (Sohia Division) family of acrylonitrile (AN) copolymerized styrene plastic. It was the first technically and commercially successful carbonated beverage bottle to be produced and was used in producing the first Coca-Cola stretched injection blow-molded bottles. See Coca-Cola bottle, barium oxide (BaO) A white to yellow powder that melts at 192°C. It forms a hydroxide with water and is used as a dehydrating agent. Also called barium monoxide or barium protoxide.

It is obtained in crystals, by boiling a strong solution of sulphuret of barium with 3UCce.s>sivo portions of black oxide (protoxide) of cc pper, until it ceases to give a black precipitate with a salt of lead. The liquid, after filtration, yields crystals of hydrate of baryta on cooling.

LEAD PROTOXIDE (1317-36-8) A strong oxidizer. Explosive reaction with 90% perox-yformic acid, rubidium acetylide. Reacts violently with strong oxidizers, boron, chlorine, fluorine, dichloromethylsilane, calcium sulfide, hydrogen peroxide, hydrogen trisulfide (ignition), hydroxylamine (ignition), lithium carbide, metal acetylides, metal powders (e.g., aluminum, molybdenum, zirconium, etc.), perchloric acid, red phosphorus, selenium oxychloride, sodium. Incompatible with aluminum carbide, barium sulfide, silicon, sulfuryl chloride. Forms impact-sensitive explosive mixtures with dichloromethylsilane. May attack plastics, coatings, and chlorinated rubber materials such as Hypalon , Parlon , Rutile , and fluorinated rubbers such as Viton . 

Barium is a metal of a dark grey colour, heavier than oil of vitriol. When exposed to the air it rapidly absorbs oxygen, forming a white powder, the protoxide of barium or baryta. It is also oxidised by water, hydrogen being liberated. 

These toxic components of the coatings can be copper oxides (I), mercury, tin-bis(tributyl)oxide, barium metaborate, anilide of salicylic acid, phenols and their derivatives, compounds of aminoformic acids, etc. [87]. In the area of metal ion toxins copper protoxide, lead and tin derivatives have recently come into extensive use.
