Kinetics of the formation conditions of carbonate tartars

Synergetic effects of temperature and magnetic field on the aragonite and calcite growth

“…As far as the temperature effect is concerned, it is well known that the formation of aragonite is favored at higher temperatures (Wray and Daniels, 1957;Roques and Girou, 1974;Kojima et al, 1992;Tai and Chen, 1998). The temperature effect on the polymorphism of CaCO 3 was first reported by Wray and Daniels in 1957.…”

Inline monitoring the effect of chemical inhibitor on the calcium carbonate precipitation and agglomeration

“…One of the primary purposes of studying the precipitation of calcium carbonate is to understand the nucleation and growth kinetics. Kinetics have often proved to be the solution to many scaling problems, as sufficient decrease in rates of nucleation and crystal growth helps to control the amount of scale formed (Roques and Girou, 1974). Various authors have studied the growth rate kinetics of calcium carbonate (Chen et al, 2005a;Roques and Girou, 1974;Mullin, 1993;Dawe and Zhang, 1997).…”

Development of scaling prediction tools for solar hot water systems. Part B - Development of an improved calcium carbonate scaling rate model - An experimental and analytical investigation

“…The only researchers who found diffusional resistances important on calcium carbonate crystal growth were Roques and Girou (1974), and it is unclear how their experimental conditions differed that would lead to this result.…”

“…However, Baker and Judd (1996c) found the growth of aragonite to be unaffected by iron compounds. Magnesium has also been found to change the dominant precipitated phase from calcite to aragonite (Roques and Girou, 1974;and Baker and Judd, 1996c). …”

“…The predominate phase to precipitate depends on the supersaturation conditions and foreign cations and impurities present (Baker and Judd, 1996c;Franke and Mersmann, 1995;Roques and Girou, 1974). The greater the supersaturation the more likely a higher volubility phase will initially fore, i.e., vaterite forms at high supersaturation levels, aragonite at moderate, and calcite at low.…”
