Barium chloride

 

Barium chloride (barium chloride) is a binary inorganic substance belonging to the class salts. The chemical formula BaCl2.

Barium chloride under standard conditions is a colorless rhombic crystals. Slightly soluble in alcohol, insoluble in diethyl ether.

Of water solutions kristallizuetsya dihydrate barium chloride — colorless crystals with monoclinic lattice. Toxic, TLV 0.5 mg/m3.

Properties barium chloride

• white crystalline powder smell;

• has a high solubility in water;

• hygroscopic;

• absorbs moisture from the air;

• toxic when ingested in the human body leads to serious poisoning;

• its aqueous solutions are neutral pH;

• can form crystalline BaCl2 • H2O and BaCl2 • 2Н2О.

Barium chloride prepared from barium hydroxide or barium carbonate, which is nature in the form of the mineral witherite. These compounds react with hydrochloric acid to the formation of hydrated barium chloride.

Getting chloride of barium occurs through the activation of the different methods and techniques, among major: interaction of metal barium and chlorine, oxide/hydroxide/barium carbonate and hydrochloric acid, barium sulfide and calcium chloride and others.

Barium chloride is solid, in the form of crystalline powder or translucent granules. The color of barium chloride white, sometimes with light grey tint. Barium chloride it is widely used in many industries and in rural economy. In the chemical industry, barium chloride is used to obtain barium salts-in the manufacture of dyes, sodium chloride and barium jet qualifications, it is also used to purify solutions from sulphates and chromates.

In addition, this reagent is used in engineering and metal working processes heat treatment products for quenching high speed tools. Barium chloride is used as heating medium in the technology of cyanidation parts and hot pressing of metals. This reagent is used to obtain a high-purity aluminum and magnesium, as shihtovogo material in color metallurgy. The barium chloride is used for dewatering and clarification of various types of leather. And of course this substance is effective in agriculture for pest control.

Barium chloride used in the manufacture of pigments (e.g., barium yellow, kiselevoj greens and other compounds), as additives in the electrolytes upon receipt of magnesium for high speed steel hardening (in the melts of mixtures of barium chloride with chlorides of alkali and alkaline earth metals), as a component of ceramics, reagent for (sulfate ions), to weight and skin lightening to tanning industry, as soiid.

Application the substance should be considered in different areas of the industry, because one is not limited to that.

Is first all of the chemical industry. Barium chloride dihydrate is used in order production of barium salts, the jet means, of various dyes, purification of brines.

It is also engineering and metallurgical industry where the connection takes participation in the quickly hardening cutting tools, heat treatment products, hot pressing of metals and cyanide components. In particular, in color metallurgy as electrolyte additive used for obtaining magnesium and super-pure aluminium.

In the textile industry barium chloride is used for the treatment of different types of skin, namely, to weight, and lightness.

Without this reagent cost and not farmers. In agriculture, the barium chloride helps in the fight against various plant pests.

For maximum effect from the use of technical chloride of barium in all of these areas need to follow some simple rules transportation, storage and use of the substance.

To carry the reagent is allowed by all kinds of roofed transport with adherence of norms nominated for transport of dangerous goods in this particular kind of vehicle.

To storage there are no special requirements. Still, barium chloride dihydrate should be stored in closed warehouses in original packaging, separately from other substances and materials. Barium chloride technical is Packed in three-layer paper bags with nested plastic bags, liners or five-layer laminated bags. It is allowed to pack the product in special soft containers one-time use.

Barium chloride is stored in closed warehouses, separately from other products.
