Examples of barium sulfate

• The open circles show the chromaticity of light reflected from a plaque of barium sulfate.

• Liquid suspensions of barium sulfate are non-toxic, apart from a small risk of producing a disturbance in bowel function for 48 hours after ingestion.

• Barium sulfate is used in some applications too.

• An exception is the administration of magnesium sulfate in barium chloride poisoning, where sulfate binds to barium to form insoluble barium sulfate.

• The brightening occurs because barium sulfate is in the form of a fine precipitate that scatters light back through the silver image layer.

• Shortly after, the process was improved; barium was removed chemically, by double precipitation from a solution as barium sulfate.

• The paste contains carbon black, "blanc fixe" (barium sulfate) and lignosulfonate.

• In colorimetry barium sulfate is used as a near-perfect diffuser when measuring light sources.

• The enema may contain barium sulfate powder, or a water-soluble contrast agent.

• Different consistencies of liquid and food mixed with barium sulfate are fed to the patient by spoon, cup or syringe, and x-rayed using videofluoroscopy.

• Barium sulfate is one of the most insoluble salts of sulfate.

• In the laboratory barium sulfate is generated by combining solutions of barium ions and sulfate salts.

• A supported palladium catalyst on barium sulfate, and doped (poisoned) with quinoline hydrogenates alkynes into "cis" -alkenes.

• As the barium sulfate doesn't dissolve, this type of contrast agent is an opaque white mixture.

• Fouling of membranes in reverse osmosis systems can occur due to differential solubility of barium sulfate in solutions of different ionic strength.
