Calcined soda, 99.4%

Chemical Formula: Na2CO3
Containers, Packaging: bags of 40 kg.
GOST / TU: GOST 5100-85
Soda ash technical (sodium carbonate) is a powder or granules of white color.

Soda ash is a hygroscopic product, absorbs air moisture and carbon dioxide with the formation of acidic salts of NaHCO3, when stored outdoors caking.

Aqueous solutions of sodium carbonate are strongly alkaline. Produce soda ash of grade A (granular) and grade B (powdered).

The area of application of soda ash
Soda ash brands A and B is used in the manufacture of glass of all types, including crystal, optical and medical glass, glass blocks, foam glass, soluble sodium silicate, ceramic tiles, Frit component for glazes; ferrous and nonferrous metallurgy: for the production of lead, zinc, tungsten, strontium, chromium, for desulphurization and deosthali cast iron, cleaning of exhaust gases, for neutralizing of environments.

For production electron-tube glass used soda ash of grade A highest grade with a strictly normalized particle size distribution.
Soda ash of grade B is used in the chemical industry for the production of synthetic detergents and fatty acids in the purification of brines in the production of phosphorus, chromium, barievykh, sodium salts such as carbonate-bearing raw material in the production of liquid allyl alcohol; pulp and paper, aniline-krasochny and paint and petroleum industries.

Packaging, transportation, storage
Soda ash is packed in paper bags weighing 50 kg, soft specialized containers of single-use mass of 800 kg (grade A) and 500 kg (grade B).

Soda ash transporterowych bulk – in soda and hoppers, Packed in soft specialized containers are transported by rail in gondola cars and boxcars.

Soda ash packed in bags is transported by any mode of transport, protecting the product from moisture. Warranty period of storage of soda ash of grade A – 3 months. grade B – 6 months packaged in soft special containers – 5 years from date of manufacture.
