· Na2CO3

Sodium carbonate (Na₂CO₃) is an inorganic ceramic compound commonly known as soda ash or washing soda, characterized by its crystalline ionic structure. It is widely used in glass manufacturing (particularly soda-lime glass for containers and windows), chemical processing, water treatment, and as a flux or additive in ceramics and metallurgy. Engineers select Na₂CO₃ for applications requiring alkalinity, thermal stability, and its role as a glass former; it is valued in industry for its availability, cost-effectiveness, and ability to lower melting temperatures in silicate systems compared to pure silica.
