Dolomitic limes: evolution of the slaking process under different conditions [PDF]

open access: yes, 2004
Dolomitic lime-based pastes were prepared in order to study the evolution of the compounds during the slaking process. Thermal studies as well as X-ray diffraction and FT-IR spectroscopy were used to confirm the formed compounds.

Heterostrukturiertes Calciumcarbonat mit Calcit‐Äquatorringen auf sphärischem Vaterit

open access: yesAngewandte Chemie, 2013
Durch Zugabe zweier verschiedener Additive wurden die im Titel bezeichneten Strukturen erhalten. Ein Bildungsmechanismus basierend auf nichtklassischer partikelvermittelter Kristallisation wird vorgeschlagen, der die individuellen und kooperativen Effekte des Polymers Poly(natrium-4-styrolsulfonat) mit der niedermolekularen Substanz Folsäure auf die ...

Growth evolution in calcium carbonate microparticles involving mixed vaterite-aragonite structures

open access: yesPhysical Review Research
Calcium carbonate (CaCO_{3}) is a widely occurring mineral that is crucial to many natural and synthetic processes. CaCO_{3} crystallizes in three anhydrous polymorphs and often serves as a model system to study nucleation and growth phenomena.
