Soda ash dense is the grade preferred for glass manufacture because its granular properties make it widely dust-free and reduce the risks of segregation during transport and handling. Sodium carbonate (Na2CO3) is used in the glass and silicate industries and also in metallurgy for its sodium oxide content (Na2O) and for its properties as a flux. It is also widely used as an alkaline reagent for the neutralization of acids and mineral or organic acid salts.
Usage: Mainly used in the glass manufacturing and crystal production industries as a melting aid.
Packing: 50kg bags, 1200kg jumbo bags.

True specific gravity 2.533 (20�°C), bulk density 0.90min. Easily soluble in water, Maximum solubility at 35.4�°C. The aqueous solution appears strong alkalinity. On exposure to air it easily absorbs moisture, carbon dioxide, and gradually forms sodium bicarbonate (caking soda).
Usage:
1.The manufacture of glass is one of the most important uses of sodium carbonate. When it is combined with silica (SiO2) and calcium carbonate (CaCO3) and heated to very high temperatures, then cooled very rapidly, glass is produced. This type of glass is known as soda lime glass.
2. Soda ash also is used to clean the air and soften water.
3. Manufacture of Caustic Soda and dyestuffs
4. metallurgy (processing of steel and extraction of iron etc),
5. (flat glass, sanitary pottery)
6. national defense (TNT manufacturing, 60% gelatin-type dynamite ) and some other aspects, such as rock oil refining, paper manufacturing, paint, salt refining, softening of hard water, soap, medicine , food and so on.
Supplier: Gypsum rocks, gypsum powder, rock salt (industrial salt and deicing salt), food grade salt, sodium bicarbonate, limestone, white limestone (marble chips), sulphur (granular, lumps)
We are glad to propose 500 MT of stain less steel mill scale.
Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products.
At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel.
The recovery ratio after melting in furnace for the most valuable alloy elements is:
- Ni: 3.5 - 4.5%
- Cr: 6-8%
From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows:
Waste code: 10 02 10
The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers.
Chemical analysis of the material is available on request.
