Commercial processes comprise more particularly reducing heavy spar by means of carbon to give barium sulfide and reacting the latter with carbon dioxide to produce barium carbonate. It has also been suggested earlier that barium sulfate be treated in an autoclave with an excess of sodium carbonate in aqueous solution at temperatures higher than 100° C and transformed into barium .

Notes. Barium carbonate powder is dense and white and is manufactured either from the mineral barite (BaSO 4) or from barium a precipitation process is used to get the carbonate form. There are several crystalline forms of BaCO 3, alpha is the most stable. Barium carbonate is very stable thermally and does not readily disassociate unless at least some CO is available in ...

Barium oxide (BaO) is formed by the oxidization of Barium salts such as barium carbonate, so the barium burns in oxygen to produce Barium oxide. Therefore, the chemical formula of Barium Oxide is BaO. The chemical reaction for the generation of Barium Oxide is as follows. 2Ba + O2 → 2BaO.

· Better results were obtained by substituting barium carbonate for K2CO3, as in the process of Margueritte and DeSourdeval (1861). Air (deoxygenated by hot carbon) was passed over a previously ignited mixture of BaCO3, ironfilings, coal tar, and sawdust, whereby barium cyanide is produced.

A nonthermal process for producing barium carbonate from barite by means of mechanochemical treatment has been developed. This process is composed of three steps: The first step is to produce barium hydroxide and potassium sulfate powders by milling of the barite and dry potassium hydroxide powder mixture in a mill.

Barium carbonate reacts with acids such as hydrochloric acid to form soluble barium salts, such as barium chloride: BaCO 3 + 2 HCl → BaCl 2 + CO 2 + H 2 O. Pyrolysis of barium carbonate gives barium oxide. Uses. It is mainly used to remove sulfate impurities from feedstock of the chloralkali process.

· The two most prevalent naturally occurring barium ores are barite (barium sulfate) and witherite (barium carbonate). In 2001, 542,000 tonnes of barium carbonate were produced globally. In Korea the estimated production volume of barium carbonate was 26 626, 10 681, and 16 452 tonnes/year in 2002, 2003, and 2004, respectively.
