Industrial uses: Other, Oxidizing agent.

Consumer uses: Oxidizing agent.

How it is made

By the action of nitric acid on barium carbonate or sulfide.

Prepared by reaction of BaCO3 and nitric acid, filtration and evaporative crystallization, or by dissolving sodium nitrate in a saturated solution of barium chloride, with subsequent precipitation of barium nitrate

For Industrial production there are two main procedures. In the first, barium carbonate is suspended in recycled mother lye and reacted with nitric acid. If necessary, heavy metals are precipitated, and the solution is filtered hot. The nitrate is then crystallized, if necessary with vacuum evaporation.

The second procedure consists of reacting a barium sulfide solution, directly or after the removal of barium hydroxide, with nitric acid. After carefully removing any sulfur formed and the heavy metals, the barium nitrate is crystallized at low temperatures. The preparation of Ba(NO3)2 by double conversion of barium chloride and sodium nitrate or calcium nitrate is described in the Eastern European patent literature.
