Calcinated soda ash 99.5% (CAS 497-19-8) is a high‑purity white powder widely used across industrial sectors. The product guarantees a minimum Na2CO3 content of 99.2% and impurity levels not exceeding 10 ppm, with full verification through TDS, SDS and COA documentation. When dissolved in water, soda ash forms a strongly alkaline solution (pH≈11.5), providing a reliable means of pH control and neutralization in many processes. In mineral flotation, the addition of Na2CO3 raises the slurry pH, disperses colloidal particles and enhances the action of collectors such as xanthates and polymeric frothers, especially in copper, lead and zinc concentrates where it is often paired with glycol‑based modifiers to improve selectivity. In glass manufacturing, soda ash acts as the primary flux, lowering the melting temperature of silica blends, reducing viscosity, and promoting a homogeneous melt; combined with limestone (CaO) and silica (SiO2) it balances the Na2O content to achieve optimal chemical durability and color stability of the final product. In detergent formulations soda ash serves as the main alkaline builder, facilitating fat emulsification and boosting surfactant performance; it is frequently used together with sodium hydroxide or sodium sulfate to create stronger alkaline systems. In water‑treatment plants soda ash precipitates calcium and magnesium as carbonate salts, effectively softening water, and is often integrated with ion‑exchange resins or polymeric media for continuous operation. The material is stored in dry, well‑ventilated facilities at +5 °C to +30 °C, packed in sealed 25 kg bags to prevent moisture uptake and preserve its chemical stability. Orders starting from 1 ton are delivered by our own fleet within 3‑5 business days to Tashkent, Almaty, Nur‑Sultan and Russian regions. Complete technical documentation is provided immediately after order confirmation, simplifying import procedures and accelerating production start‑up.

Store the calcined soda in a dry, well‑ventilated area with ambient temperatures typical for warehouse storage (approximately 20‑25 °C). Keep the packaging tightly sealed and protected from moisture and direct sunlight to avoid caking and loss of purity. When these conditions are maintained, the product generally retains its quality for 12‑24 months. During handling, wear protective gloves, goggles and a mask, prevent contact with water or acidic substances, and ensure pallets are securely stacked to preserve package integrity.
