CORROSION CONTROL: Using Caustic Soda to Control Corrosion
Caustic soda, or sodium hydroxide (NaOH), will increase the pH of the water without adding calcium ions that are needed for calcium carbonate precipitation to occur. Consequently, for a given pH adjustment, caustic soda should reduce the calcium carbonate precipitation potential compared to lime.

Sodium Carbonate Vs Calcium Hydroxide - FAQ - All your
May 25, 2020· 3. The resulting material should have lost around third of the original weight. It will be of a slightly less powdery consistency, closer to sugar than flour. * sodium carbonate feels a bit looser and grainier than bicarbonate, and in an oversaturated solution, sodium bicarbonate will remain powdery while sodium carbonate tends to rock up.
Buy China Industrial grade Sodium Carbonate Light Company
The manufacture of glass is one of the most important uses of sodium carbonate.When it is coined with silica(SiO2) and calcium carbonate (CaCO3) and heated to very high temperatures,then cooled very rapidly, glass is produced. This type of glass is known as soda lime glass.
Sodium and carbonate distribution in substituted calcium
The cell parameters of the lower carbonate content apatite are a=9.3892(4) and c=6.9019(3) Å, while those of the higher one are a=9.3249(1) and c=6.9213(1) Å. Occupancy factors show that sodium is localised mainly in a 6h ionic site. Furthermore, carbonate ions occupy phosphate sites leading to a B-type carbonate apatite.
