Barium nitrate inhalation, it can still result in irritation, itching, redness, and pain. The Occupational Safety and Health Administration and the National Institute for Occupational Safety and Health have set occupational exposure limits at 0.5 mg/m over an eight-hour time-weighted average. Barium nitrate Barium nitrate is the inorganic compound with the chemical formula Ba(NO). It, like most barium salts, is colorless, toxic, and water-soluble. It burns with a green flame and is an oxidizer; the compound is commonly used in pyrotechnics. Barium nitrate is manufactured by two processes that start with the main source material for barium, the carbonate. The first involves
Barium sulfate mixture and make it hard to see the color of the indicator. Barium sulfate added to the mixture binds with these particles, making them heavier so they fall to the bottom, leaving a clearer solution. In colorimetry, barium sulfate is used as a near-perfect diffuser when measuring light sources. In metal casting, the moulds used are often coated with barium sulfate in order to prevent the molten metal from bonding with the mould. It is also used in brake linings, anacoustic foams, powder coatings, and root canal filling. Barium sulfate is used as a catalyst support when selectively hydrogenating functional
