99% Barium carbonate powder BaCO3 can make as the material of ceramic glaze and rat poison ►Description

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.

There have three different powder as below :

• Barium carbonate standard powder is used in the production of special

glass, glazes, brick and tile industry, ceramic and ferrite industry, also used for

removing of sulfates in phosphoric acid production and chlorine alkali electrolysis

• Barium carbonate fine powder is specially developed for usage in the brick

and tile industry and for the removing of sulfates.Other applications are in the

ceramic and ferrite industry. It is also used in the production of chlorine alkali

electrolysis and for the purification of phosphoric and tartaric acid.

• Barium carbonate granular is used for the production of display glass,

crystal glass and other special glass, glazes, frits and enamels, also used in the

chemical industry.

►Specification

►Methods of manufacturing

Barium carbonate is made from barium sulfide soln by one of two methods.

In the first, the soda ash method, the barium sulfide soln is treated with sodium

carbonate, either dissolved or in solid form, producing barium carbonate and

sodium disulfide.The usual operating temp is 60-70 deg C. The resulting slurry is

filtered and the barium carbonate is washed, dried, ground, and packaged. This

process is thought to be used by about half of the industry .

In the second main method, carbon dioxide gas is passed through a barium sulfide

soln, either batchwise or on a continuous basis, at 40-90 deg C. Temp and other

operating conditions have a pronounced effect on the size and characteristics of the

particles formed. To obtain a satisfactory product, the barium sulfide must react with

slightly less than the stoichiometric amt of carbon dioxide; the carbon dioxide may

be supplied in pure form, or may be obtained from the combustion gases of barium

sulfide reduction kilns.

►Application

Barium carbonate was mainly used in ceramic glazes, cement, bricks and in rat

poison.

►Notice

First Aid

Rapid oral administration of a soluble sulfate in water, such as magnesium or

sodium sulfate (2 oz), alum (4 gm), or very dilute sulfuric acid (30 ml of a 10%

solution diluted to 1 qt). These agents precipitate barium as the insoluble sulfate.

Gastric lavage or induced emesis. Seek medical attention.

Air & Water Reactions

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

Fire Hazard

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. For electric

vehicles or equipment, lithium ion batteries or sodium batteries should also be

consulted.

Health Hazard

(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.

Reactivity Profile

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.
