Product Overview
Sodium Carbonate Anhydrous, also known as soda ash or calcined soda, is a highly versatile inorganic compound widely used across chemical manufacturing, food processing, pharmaceuticals, and water treatment. As the water-free form of sodium carbonate, it offers greater purity and stability, making it suitable for applications requiring minimal moisture content.
This compound functions primarily as a pH regulator, buffering agent, cleaning aid, and mineral source, depending on the industry and formulation.
