Soda Ash (Calcium Carbonate)

Description

Top Grade Alkali Source for Industrial Manufacturing & Processing

Soda Ash (Na₂CO₃), chemically known as sodium carbonate, is a white, odorless, hygroscopic powder that ranks among the most important industrial chemicals globally. This essential alkali provides superior pH control, water softening, and chemical processing capabilities across diverse industries. With over 50% of global production dedicated to glass manufacturing, Soda Ash serves as the primary flux that reduces silica melting temperatures and controls glass viscosity. Beyond glass production, sodium carbonate finds extensive use in detergent formulation, chemical synthesis, water treatment, metallurgy, and food processing due to its excellent solubility, alkaline properties, and chemical stability.
