Sodium carbonate (Na₂CO₃), commonly known as soda ash or washing soda, is an inorganic ceramic compound that serves as a foundational material in glass manufacturing and chemical processing. It is widely used in the production of soda-lime glass for containers and flat glass applications, as well as in detergents, water treatment, and metallurgical processes where its alkalinity and thermal stability are essential. Engineers select sodium carbonate for applications requiring alkaline pH control, flux properties in metalworking, or as a precursor chemical where its relatively low cost and availability make it more economical than specialized ceramic alternatives.
