Soda Ash Dense 99.2% (Sodium Carbonate)

Soda Ash Dense 99.2% (Sodium Carbonate) (CAS 497-19-8, molecular formula Na2CO3) is a core commodity reagent used wherever reliable acid or alkali strength matters — from surface treatment and pH correction to downstream salt manufacture. China Chemicals supplies it at 99.2% min in pack sizes from 1 kg through to 1000 kg Bulk Bag, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as Sodium Carbonate, Washing Soda, Disodium Carbonate. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.

Typical applications

Container and flat glass manufacture
Detergent builder and water softening
pH buffering in pool and process water
Sodium silicate and sodium bicarbonate production
Flue gas desulphurisation
