Metabolism/Metabolites · 1 件

Barium compounds are absorbed via ingestion and inhalation, the extent of which depends on the individual compound. In the body, the majority of the barium is found in the bone, while small amounts exists in the muscle, adipose, skin, and connective tissue. Barium is not metabolized in the body, but it may be transported or incorporated into complexes or tissues. Barium is excreted in the urine and faeces. (L214)

解説酸化バリウム，白色の粉末．密度5.72 g cm－3．融点1923 ℃，沸点約2000 ℃．水に溶かすとはげしく反応して水酸化バリウムを生じる．酸と反応してバリウム塩を生じる．空気中に放置すると二酸化炭素を吸収して炭酸バリウムとなる．森北出版「化学辞典（第2版）

使用Barium oxide is used as a coating for “hot cathodes” in a variety of electronic devices such as TV’s and lamps. It replaced lead oxide in the production of certain kinds of glass. While lead oxide raised the refractive index of the glass, it also raised the dispersion, i.e refraction of various colors of light resulting in distortion of images which barium oxide does not alter. Barium oxide also has use as an ethoxylation catalyst in the reaction of ethylene oxide and alcohols which takes place between 150 and 200°C. The thermionic emission from thin evaporated films of barium oxide has been studied extensively. Thin barium oxide films have a good emission following evaporation. The emission improves a little during heat treatment, and is then similar to that from a sprayed cathode coating of barium oxide.

Reactivity Profile · 1 件

BARIUM OXIDE reacts as a strong base. Combines exothermically with all categories of acids. Reacts with carbon dioxide to form barium carbonate [Merck 11th ed. 1989]. Ignites hydroxylamine on contact [Mellor 8:291 1946-47]. Mixtures with mercurous or nickel oxide react vigorously with hydrogen sulfide in air. Explosions may result [Mellor 10:140 1946-47]. Can react, particularly in the presence of moisture, with aluminum and zinc)to form oxides or hydroxides of the metal and generate gaseous hydrogen. May initiate polymerization reactions in polymerizable organic compounds, especially epoxides. May generate flammable and/or toxic gases with ammonium salts, nitrides, halogenated organics, peroxides, and hydroperoxides.

Chemical DangersThe solution in water is a medium strong base. Reacts violently with water, dinitrogen tetraoxide, hydroxylamine, sulfur trioxide and hydrogen sulfide. This generates fire and explosion hazard.

毒性情報

TreatmentIntravenous infusion of potassium often relieves many of the symptoms of barium toxicity. (L214)
Health Effects · 1 件

The health effects of the different barium compounds depend on how well the compound dissolves in water or the stomach contents. At low doses, barium acts as a muscle stimulant, while higher doses affect the nervous system, causing cardiac irregularities, tremors, weakness, anxiety, dyspnea, paralysisand possibly death. Barium may also cause gastrointestinal disturbances, damage the kidneys and cause decreases in body weight. (L214)

Adverse EffectsNephrotoxin - The chemical is potentially toxic to the kidneys in the occupational setting.
Exposure Routes · 2 件

The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

Oral (L214) ; inhalation (L214)

Toxicity Summary · 1 件

Barium is a competitive potassium channel antagonist that blocks the passive efflux of intracellular potassium, resulting in a shift of potassium from extracellular to intracellular compartments. The intracellular translocation of potassium results in a decreased resting membrane potential, making the muscle fibers electrically unexcitable and causing paralysis. Some of these barium's effects may also be due to barium induced neuromuscular blockade and membrane depolarization. (L214)

Signs and Symptoms · 5 件

Cough. Sore throat.

Redness. Pain.

Redness. Pain.

Abdominal pain. Diarrhoea. Nausea. Vomiting. Muscle paralysis. Irregular heartbeat. Elevated blood pressure.

Ingesting excess barium may cause vomiting, abdominal cramps, diarrhea, difficulties in breathing, increased or decreased blood pressure, numbness around the face, and muscle weakness. High levels may result in changes in heart rhythm or paralysis and possibly death. (L214)

ICSC Environmental DataThe substance is harmful to aquatic organisms.
Carcinogen ClassificationNo indication of carcinogenicity to humans (not listed by IARC).
Toxicity DataLD50: 50 mg/kg (Oral, Rat) (L274)
