Electrokinetic behaviour of calcite—the relationship with other calcite properties

Chemical Geology, 2001
Six carbonate samples of different origin were investigated for their properties: composition, grain-size (Mz), specific surface area (SSA) and electrokinetic (zeta) potential. Four of the samples were of natural origin – one sample was sea sediment, one lake sediment and two limestone rocks. The remaining two samples were synthetic calcites.

Mesoporous Calcite by Polymer Templating

Crystal Growth & Design, 2008
Layered calcite crystals with internal 10−50 nm pores are precipitated from aqueous solution containing a polymer−peptide conjugate that aggregates into pore-forming templates. The zwitterionic peptide sequence behaves as the “binding block” of a double-hydrophilic block copolymer, facilitating templating, nucleation inhibition, and stabilization of ...

Recrystallization of Magnesian Calcite Overgrowths on Calcite SeedsSuspended in Seawater

Aquatic Geochemistry, 1998
The formation and subsequent reactions of magnesiancalcite overgrowths on calcite were investigated bymeans of closed system seeded precipitationexperiments. These experiments demonstrated that(1) thin overgrowths of magnesian calcite are precipitatedon calcite seeds suspended in seawater;(2) the solubilities of the coatings increase outward from ...

Etching of Calcite

Nature, 1959
EXPERIMENTS on etching of calcite have been carried out earlier by a number of workers1 and etch pits on calcite have been reported recently by H. Watts2 and R. C. Stanley3. We have been carrying out experiments on etching of mineral crystals with different etching reagents for some time and have investigated calcite very thoroughly.
