Aragonite — Wikipédia

L'aragonite est le polymorphe stable à haute température et haute pression du carbonate de calcium, de formule CaCO 3 ; le polymorphe stable en conditions ambiantes est la calcite.L'aragonite est néanmoins métastable en conditions ambiantes (il se transforme en calcite en plusieurs dizaines voire centaines de millions d'années).; Les trois formes principales …

Control of Aragonite or Calcite Polymorphism by Mollusk Shell

Many mineralizing organisms selectively form either calcite or aragonite, two polymorphs of calcium carbonate with very similar crystalline structures. Understanding how these organisms achieve this control has represented a major challenge in the field of biomineralization. Macromolecules extracted from the aragonitic shell layers of some ...

(DOI: 10.1007/S12613-018-1692-6) In pyrometallurgical process, Al- and Si-bearing minerals in iron and aluminum ores are easily transformed into sodium aluminosilicates in the presence of Na2O constituents, which alters the leaching behaviors of Al2O3 and SiO2. It was confirmed that sodium aluminosilicates with different phase compositions synthesized at various roasting …

Traitement de l'aragonite

L'aragonite est un minéral carbonaté, l'un des deux polymorphes courants et naturels du carbonate de calcium, CaCO3. L'autre polymorphe est la calcite. Le réseau cristallin de l'aragonite diffère de celui de la calcite, ce qui se traduit par une forme cristalline différente, un système orthorhombique avec des cristaux aciculaires.
