Exempel på hur man kan använda BARIUM i en mening

• Its physical and chemical properties are most similar to its heavier homologues strontium and barium.
• He is also remembered for isolating, by using electricity, several elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as for discovering the elemental nature of chlorine and iodine.
• Strontium has physical and chemical properties similar to those of its two vertical neighbors in the periodic table, calcium and barium.
• They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
• 63 g, but calcium (Ca) can substitute for up to 27% of the strontium (Sr) cations, and barium (Ba) up to 3.
• Scheele discovered oxygen (although Joseph Priestley published his findings first), and identified molybdenum, tungsten, barium, nitrogen, and chlorine, among others.
• For example, unbinilium is expected to be less reactive than barium and radium and be closer in behavior to strontium, and while it should show the characteristic +2 oxidation state of the alkaline earth metals, it is also predicted to show the +4 and +6 oxidation states, which are unknown in any other alkaline earth metal.
• In standard medicine, the most frequent uses of enemas are to relieve constipation and for bowel cleansing before a medical examination or procedure; also, they are employed as a lower gastrointestinal series (also called a barium enema), as treatment for encopresis, and as a form of rehydration therapy (proctoclysis) in patients for whom intravenous therapy is not applicable.
• The main class of high-temperature superconductors is copper oxides combined with other metals, especially the rare-earth barium copper oxides (REBCOs) such as yttrium barium copper oxide (YBCO).
• A similar pattern was found with calcium, strontium, and barium; with sulfur, selenium, tellurium; and with chlorine, bromine, and iodine.
• Synthetic barium chlorapatite, strontianite, and fluorapatite were used as standards for the elements they contain.
• To identify the cause of gastric distention, an upper endoscopy or barium upper GI imaging should be done.
• When a barium chloride solution reacts with sulphuric acid, a white precipitate of barium sulphate is formed.
• Late in 1987, he joined a research team under Didier de Fontaine which was using similar Monte Carlo methodology to investigate the superconducting properties of yttrium barium copper oxide, modelling transitions between ordered and disordered phases.
• Its color gradually changes to yellow with aging, whereas contamination by barium may impart a rose tint.
• Radiographs (X-ray pictures) are taken while barium sulfate, a radiocontrast agent, fills the colon via an enema through the rectum.
• Historians have speculated that Lawrence’s exposure to the toxic chemicals used in paint in the 1800s (including lead, antimony, chromates, sulfides and barium) contributed to his mental illness, which manifested itself when he was in his thirties.
• It is part of the more general group of rare-earth barium copper oxides (ReBCO) in which, instead of yttrium, other rare earths are present.
• Mixing the two compounds forms a barium sulfate precipitate, which causes turbidity in the solution.
• A material he was working with, barium titanate, underwent unusual structural changes when it became ferroelectric, requiring Last to study it using infrared spectroscopy.
