“…Different of added mode lead to excessive Ca 2+ and CO 3 2À in the reaction system so that two different crystalline calcium carbonate products are obtained. 37 By the eqn (4) computed value of calcite approximately (100%) and vaterite approximately (100%) revealed that the products were pure phase of calcite and vaterite was consistent with that of XRD in Fig. 12a and b, respectively.…”

“…Indeed, many water soluble additives or polyelectrolytes may influence crystal growth mechanism, nucleation, shape and size of the crystals [34] and polymorph of calcium carbonate [35]. Additives commonly used for scale inhibition are polymers containing carboxylic acid groups such as polyacrylic acid [36][37][38], polymaleic acid [38] and polyaspartic acid (PASP) [15,39].…”

International audienceIn this paper, the inhibition efficiency of two inhibitors, namely poly(acrylic acid-co-maleic acid) and polyaspartic acid, towards calcium carbonate scaling was evaluated using fast controlled precipitation (FCP) method and electrochemical quartz crystal microbalance (EQCM). FCP method gave some insight to the calcium carbonate precipitation in solution, whereas EQCM was used to study the calcium carbonate formation on a metallic substrate. It has been shown that these polymers were efficient to delay or to prevent nucleation/growth process, depending on their concentration. Moreover they significantly decreased the crystal growth rate. The FCP method showed that these inhibitors were very efficient at low concentrations (4 mg L−1) when no precipitation occurred. In addition, EQCM showed that the surface coverage of deposits on a substrate was reduced by the presence of these inhibitors at very low concentration (4 mg L−1). Scanning electronic microscopy and X-ray diffraction showed that the presence of these polymers modified the morphology of calcium carbonate crystal. In order to model nucleation/growth process of calcium carbonate on surface, mass–time transients were interpreted using a 3D model based on a nucleation following a Poisson law associated to vertical and lateral growth rates

“…Controlling the operation conditions, like temperature, pH, and supersaturation, or adding crystalline regulator, it can influence nucleation, formation, and the final polymorph of calcium carbonate [6]. Commonly used crystalline regulators include chelating agent [7], organic compound [8,9], inorganic salt, minerals, organic acid [10], alcohol, amino acid [11], and chitosan. The morphology of calcium carbonate can also be induced by biological factors [12].…”

Ultrafine calcium carbonate is a widely used cheap additive. The research is conducted in low degree supersaturation solution in order to study the polymorphic phases’ change and its factors of the calcium carbonate precipitate in the ammonification-carbonization process of the solution with calcium. Fine particles of calcium carbonate are made in the solution containing 0.015 mol/L of Ca2+. Over 98% of the calcium carbonate precipitate without ammonification resembles the morphology of calcite, while the introduction of ammonia can benefit the formation of vaterite. It was inferred that the main cause should be serious partial oversaturation or steric effects. Ammonia also helps to form the twin spherical calcium carbonate. However, particles formed in the process of ammonification-carbonization in solution with low concentration degree of calcium are not even with a scale of the particle diameter from 5 to 12 μm. Inorganic salts, alcohol, or organic acid salts have significant controlling effect on the particle diameter of calcium carbonate and can help to decrease the particle diameter to about 3 μm. Anionic surfactants can prevent the conglobation of calcium carbonate particles and shrink its diameter to 500 nm–1 μm.
