Sodium Carbonate or Natural Soda Ash (based on Trona) are present in a wide range of applications. They are already well-known for their effectiveness in flux for glass and flux for silicate. Moreover, they are also playing another role: a chemical that can substitute caustic soda and increase PH.

In which consumer markets is Soda Solvay® usually present?

• Glass Industry – Raw material for melting and flux agent to reduce the melting point of silica (and consequently reduces energy consumption) 
• Detergents – Alkaline support, grease removal (saponification effect), water softening
• Chemical Industry – Acting as a strong base (increases pH) with a softer effect compared to caustic soda
• Metallurgical processes – Desulfurization of pig iron, flux agent for mineral extraction, production of Lithium Carbonate …  
• Pulp & Paper - Can substitute caustic soda
• Supplement in pharma – High purity carbonate IPH is used as an Active Pharmaceutical Ingredient (API) to enable tabletting  (effervescent tablets)
