Total annual world manufacturing estimated around 6,000,000 tons. Key mining locations are UK, Italy, Czech Republic, USA and Germany. Total human being reserves estimated to be about 450,000,000 tons.Uses that Barium:Used in sparkplugs, vacuum tubes, fireworks, fluorescent lamps. Insoluble barium sulfate is offered for body imaging.Additional Notes:Must be stored under kerosene to continue to be pure. Soluble barium salt are highly toxic.
