Effects of pH on precipitation of quasi-crystalline
Dec 01 2000 · C-S-H samples were precipitated from aqueous solution containing Ca(NO 3) 2 and Na 2 SiO 3 with an initial Ca/Si molar ratio of 1·3 when the pH value in the solution was varied by adding HNO 3 or NaOH. A pH > 10·9 was required to obtain quasi-crystalline C-S-H and the CaO/SiO 2 ratio of the precipitate was increased with increasing pH reaching a maximum close to the initial ratio at pH > 13.

Calcium silicate neutralizes active acidity in AMD systems by removing free hydrogen ions from the bulk solution thereby increasing pH. As its silicate anion captures H ions (raising the pH) it forms monosilicic acid (H 4 SiO 4) a neutral solute. Monosilicic acid remains in the bulk solution to play other important roles in correcting the

Calcium is the most complex and difficult of all the pool stain issues we treat because calcium can form in a pool for a variety of reasons. White calcium (or scale) can form because pool owners often have difficulty keeping their pH in balanceparticularly when their pool is new. High pH is a major reason for calcium formation and growth.

How to Defeat Calcium Scaling in Your Swimming Pool
Calcium carbonate is white and flaky and it s fairly easy to take off. Calcium silicate in contrast is white-grey and more difficult to move. Additionally because calcium silicate takes longer to form pools that have calcium silicate buildup on their walls often also have scaling in their pipes.
