Aragonite Use In Plastics

Supersaturation control in aragonite synthesis

15.10.2003· 1.. IntroductionInexpensive calcium carbonate has been widely applied as a filler in paper, plastics, and rubber. It was thought that needle-like calcium carbonate filler might give excellent properties to paper for bulk, brightness, opacity, and strength, as well as improved retention,,,, .Gill and Scott found that PCC of the aragonite and scalenohedral forms was superior to rhombohedral

A mild route for the preparation of calcium carbonate rod

has been widely used in rubber, plastics, coatings, paper, ink, and other industries. CaCO 3 has various crystal forms, includ-ing calcite, aragonite, and vaterite. As to the aragonite, it is unstable and easy to turn into calcite in nature [4], which belongs to the orthorhombic system and mainly performs as

Aragonite

Aragonite is also used to knock down sulfurous gases in power plants, where it is converted to calcium sulfate or gypsum. The fines are sometimes used as extenders in linoleum manufacture, in place of more expensive plastics, etc. Aragonite is no longer in big demand for several of these uses.

Synthesis of aragonite by carbonization from

10.09.2013· 1. Introduction. Calcium carbonate (CaCO 3) is a chemical industrial product that is extensively used as a novel functional material in fields such as plastics, rubber, paint, ink, weaving, toothpaste, make-up, and foodstuffs.It has three polymorphs, calcite, aragonite, and vaterite, which have trigonal, orthorhombic, and hexagonal crystal system, respectively.

ELASTIC PROPERTIES OF NACRE ARAGONITE TABLETS

for aragonite were used in the model. The most relevant approach for this case was to assume that the presence of intracrystalline molecules within the tablets would affect their elastic properties altogether. Fig.5b shows the results for the Hanson model using the elastic constants found above (E z = 82 GPa, E p = 107 GPa, p ν= 0.25, ν

Accurate Radiocarbon Dating of Archaeological

Pyrogenic aragonite, another mineral phase recently discovered in ash, might preserve its 14 C signature through time. Using a new method based on density separation and step combustion, we were able to isolate and date aragonitic ash from an archaeological destruction horizon of known age.

Aragonite - an overview | ScienceDirect Topics

Aragonite whiskers are considered as reinforcements for polymer composites used in structural engineering applications. Hashimoto and Yamaguchi (1995) synthesized magnesium aluminate (MgAl 2 O 4 ) whiskers by an oxidation–reduction reaction between MgO, C, and Al in a CO+CO 2 atmosphere.
