Barium in a sentence

Further refinements of the technique, leading to the decisive experiment on 16–17 December 1938 (the celebrated "radium-barium-mesothorium-fractionation"), produced puzzling results: the three isotopes consistently behaved not as radium, but as barium.

It is also used to produce other barium chemicals, notably barium carbonate which is used for the manufacture of LED glass for television and computer screens ( historically in cathode ray tubes); and for dielectrics.

Of the stable isotopes, barium-138 composes 71.7% of all barium, and the lighter the isotope, the less abundant.

The discovery was announced by Davy on 30 June 1808 at a lecture to the Royal Society. citation Barium Barite, the material that was first found to contain barium.

The remaining residue was then treated with sodium carbonate to convert the barium sulfate into barium carbonate carrying the radium, thus making it soluble in hydrochloric acid.

Ultrapure barium is very difficult to prepare, and therefore many properties of barium have not been accurately measured yet.

Dried soil, barium sulphate and indicator fluid ready for a shake.

The report indicates that there were no violations of contaminant thresholds for Lead, Copper, Barium, Nitrates, Trihalomethane, Haloacetic Acids, Fluoride, or Chlorine in Hastings drinking water.

Light: Advanced Manufacturing, a team of researchers, led by Professor Junjia Wang from Southeast University, and Professor Guohua Dong from Xi'an Jiaotong University, have proposed a new way to transfer barium titanate onto silicon.

They found increased salinity and high concentrations of heavy metals in water nearer oil wells, as well as high concentrations of lead and barium in human hair samples.

This is because the Supreme Court had reiterated its ban on barium nitrate, a key ingredient in the manufacture of crackers, and imposed restrictions on joined crackers.

The chemicals of concern impacting soil consist of pesticides, semi volatile organic compounds silver, arsenic, barium, cadmium, PCBs, selenium, and mercury.

Geochemical sampling has defined coincident gold, arsenic, antimony, silver, mercury and thallium soil anomalies bordered by barium and copper anomalies.

Shockingly, Barium was also found in the air collected post-Diwali.

In the meantime, untold tons of ash contaminated with dangerous compounds such as barium, lead, and arsenic were buried under Miami's parks.

Adding barium also increases the refractive index.

Additionally, radium phosphate, oxalate, and sulfite are probably also insoluble, as they coprecipitate with the corresponding insoluble barium salts.

After dissolution the barium and radium are reprecipitated as sulfates and this was repeated one or few times, for further purification of the mixed sulfate.

A " getter ", a small amount of shiny barium metal evaporated onto the inside of the glass, helps maintain the vacuum by absorbing gas released in the tube over time.

Anything that may contact with barium should be electrically grounded.
