Dense soda ash produced by TCNA is high-quality soda ash that is primarily used in the production of glass. Dense soda ash is generally preferred over light soda ash in glass manufacture, because the particles are of a similar size to silica sand. This enables a homogeneous mixing of raw materials and results in a high-quality end product.
Tata Chemicals North America makes high-quality soda ash that is in demand by several industries in the US as well as the export market. The soda ash produced in the US is natural soda ash, which requires much less energy, capital and raw materials than synthetic soda ash production, and is a significantly less-costly process.
