설명

일반 설명

Sodium carbonate (Na₂CO₃) is an inorganic compound also known as soda ash. It is used in flue gas desulfurization, and in detergent formulations. It is a stronger alkali used as a softening agent in laundry detergents.

애플리케이션

Sodium carbonate can be used:

• A sintering aid with the ZnO (zinc oxide) for the preparation of BaCe_0.5Zr_0.3Y_0.2O_3−δ based composite electrolyte material by solid-state reaction.
• A co-precipitating agent for the synthesis of stable iron oxide nanoparticles from a stoichiometric combination of Fe(II) and Fe(III) salts.
• A catalyst for the etherification of glycerol to polyglycerols.
