説明

Barium carbonate has the molecular formula of BaCO3 and the molecular weight of 197.3359 g/mol. Its CAS number is 513-77-9. Barium carbonate has only one stable form (aragonite-type structure) and temperature of precipitation has no effect on crystal form, unlike that of calcium or magnesium carbonates.

化学的特性

Barium carbonate, BaCD3, also known as witherite,is a white powder that is soluble in acids,with the exception of sulfuric acid.It has a melting point of 174°C and is used in television picture tubes, rodenticide, optical glass and ceramic flux.

使用

Preparation of barium standard solution. It is used in ceramic glazes, cement, bricks and in rat poison.

使用

Rat poison; in ceramics, paints, enamels, marble substitutes, rubber; manufacture of paper, barium salts, electrodes, optical glasses; as an analytical reagent.

使用

Barium carbonate has many major commercial applications in brick, glass, ceramics, oil-drilling, photographic and chemical industries. It is mixed with wet clay to immobilize many water-soluble salts in making uniform red bricks. In the glass industry, barium is added to glass as barium carbonate or barium oxide to improve the refractive index of optical glass and also to promote sintering and lower the viscosity of melted glass to make glass bead formation easy. It is used in the manufacture of television picture tubes and photographic paper. Another important application involves its use as a fluxing ingredient in ceramic industry for enamels, glazes and ceramic bodies. Barium carbonate is used in oil well drilling to insolubilize gypsum and inhibit coagulation; in ferrous metallurgy for steel carburizing; in chloralkali cells for treating salt brines to remove sulfates; and to make ferrites, and barium titanate. Many barium salts are prepared from barium carbonate.

製造方法

Barium carbonate is made commercially from barium sulfide either by treatment with sodium carbonate or ammonium carbonate at 60 to 70°C or by passing CO2 gas through a soluble Ba2+ solution at 40 to 90°C.

定義

barium carbonate: A white insolublecompound, BaCO3; r.d. 4.43. It decomposeson heating to give bariumoxide and carbon dioxide:
BaCO3(s) → BaO(s) + CO2(g)
The compound occurs naturally asthe mineral witherite and can be preparedby adding an alkaline solutionof a carbonate to a solution of a bariumsalt. It is used as a raw materialfor making other barium salts, as aflux for ceramics, and as a raw materialin the manufacture of certaintypes of optical glass.

定義

witherite is a mineral form of bariumcarbonate, BaCO3.

一般的な説明

Barium carbonate is a white powder. Barium carbonate is insoluble in water and soluble in most acids, with the exception of sulfuric acid. Barium carbonate has a specific gravity of 4.275. Barium carbonate is toxic by ingestion.

空気と水の反応

Barium carbonate is insoluble in water and soluble in most acids, with the exception of sulfuric acid.

反応プロフィール

Salts, basic, such as Barium carbonate, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.

危険性

A poison.

健康ハザード

(INGESTION ONLY): excessive salivation, vomiting, severe abdominal pain, and violent purging with watery and bloody stools; a slow and often irregular pulse and a transient elevation in arterial blood pressure; tinnitus, giddiness and vertigo; muscle twitchings, progressing to convulsions and/or paralysis; dilated pupils with impaired accommodation; confusion and increasing somnolence, without coma; collapse and death from respiratory failure and cardiac arrest.

火災危険

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

安全性プロファイル

Poison by ingestion, intravenous, and intraperitoneal routes. Human systemic effects by ingestion: stomach ulcers, muscle weakness, paresthesias and paralysis, hypermotility, diarrhea, nausea or vomiting, lung changes. Experimental reproductive effects. Incompatible with BrF3 and 2- furanpercarboxylic acid. See also BARIUM COMPOUNDS (soluble).
