Growth behavior of aragonite under the influence of magnetic field, temperature, and impurity / Steven S.S. Wang in Industrial & engineering chemistry research, Vol. 51 N° 2 (Janvier 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 2 (Janvier 2012) . - pp. 1041-1049 Titre : Growth behavior of aragonite under the influence of magnetic field, temperature, and impurity Type de document : texte imprimé Auteurs : Steven S.S. Wang, Auteur ; Meng - Chun Chang, Auteur ; Huan - Chieh Chang, Auteur Année de publication : 2012 Article en page(s) : pp. 1041-1049 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Impurity  Magnetic  field Résumé : With and without magnetization, the growth rates of aragonite seeds were measured in a stirred-tank crystallizer in the presence of Fe2+ or Sr2+ acting as an impurity at two temperature levels, using the constant-composition technique. The concentration range of the impurity investigated was between 0 and 2 ppm, and the temperature settings were either 25 or 35 °C. The individual factors each had a distinct effect on the growth rate of aragonite, and the combined effects became complicated, especially in the presence of Sr2+, which changed the surface structure of the aragonite seed dramatically.
