CAS 497-19-8
Soda Ash
Soda Ash (sodium carbonate) is a core alkali for glass, detergents and chemicals, and for pH control in mining and water treatment, supplied in light and dense grades.
Soda ash, Na₂CO₃, is one of the most widely used industrial chemicals. It is produced as a fine light grade and as a dense grade with larger, heavier granules. The chemistry is the same; what differs is bulk density and particle size, which decide how it handles, blends and dusts.
Dense soda ash dominates glass making, where it must blend evenly with sand without segregating or dusting in the furnace. Light soda ash dissolves faster and is preferred in detergents, sodium silicate and chemical manufacture. In mining it adjusts flotation pulp pH, and in water treatment it raises alkalinity and softens hard water.

Storage & handling
Store dry. Soda ash absorbs moisture and carbon dioxide from the air and will cake if bags are damaged. It is not classed as dangerous goods but is an eye irritant.

Soda Ash — frequently asked
Light and dense soda ash are chemically identical sodium carbonate. Light soda ash has a bulk density of about 0.5–0.65 g/cm³ and dissolves quickly; dense soda ash is about 0.9–1.1 g/cm³ with larger granules that flow well and produce less dust.
Dense soda ash has a particle size close to that of glass sand, so the batch mixes evenly and does not segregate. It also produces far less dust in the furnace, reducing carry-over and refractory attack.
No. Soda ash is not regulated as dangerous goods for sea freight. It is an eye irritant, so dust masks and goggles are recommended when handling it.
