Kaolinite - Wikipedia, the free encyclopedia Kaolinite is a clay mineral with the chemical composition Al Kaolinite is one of the most common minerals; it is mined in Brazil, France, Britain, Germany, India, Australia, Japan, China, and the southeastern U.S. states of Georgia, Florida, and, to a lesser extent, South Carolina. While a single magazine made using kaolinite does not contain enough radioactive material to be detected by a security-oriented monitor, this does result in truckloads of high end glossy paper occasionally tripping an overly-sensitive radiation monitor. en.wikipedia.org /wiki/Kaolin   (425 words)

Kaolinite (Kaori Kuromine) - Member of the Death Busters Kaolinite then waited patiently for her selected target's appearance to awaken the Daimon Mikuuji to life and only remained long enough to make certain that the young girl was unable to escape from the monster's clutches as it extracted her Heart Crystal before departing to locate her next victim. Even so, Kaolinite probably did derive some small degree of satisfaction from the fact that she was blameless in her unsuccessful subsequent attempt on volleyball player Tsutomu Asai and the failure of the Daimon Highkyuun to eliminate him, Sailor Venus, or the other Sailor Soldiers, as the target had been suggested by the professor himself. When Kaolinite next appeared before Professor Tomoe, she told him that she had found a potential victim of such pureness of heart that she was positive that the individual in question was one of the three Talisman holders the Death Busters had been searching for. www.fortunecity.com /rivendell/everquest/90/K/kaolinite.html   (1502 words)

Kaolinite Data   (Site not responding. Last check: 2007-11-07) Kaolinite is a clay mineral, as are illite and smectite. Kaolinite is formed by the alteration of alumino-silicate minerals, primarily feldspars. Kaolinite is used in a variety of industrial processes, from the manufacture of pencil lead to making the paper in magazine pages shiny. www.uwm.edu /Course/422-100/Mineral_Rocks/kaolinite.data.html   (153 words)

USGS OFR01-041: Kaolinite-Group Minerals The kaolinite group includes the dioctahedral minerals kaolinite, dickite, nacrite, and halloysite, and the trioctahedral minerals antigorite, chamosite, chrysotile, and cronstedite. All members of the kaolinite group form primarily during hydrothermal alteration or weathering of feldspars under acid conditions; but kaolinite and halloysite are probably the only members formed in soils (Deer and others, 1975; Swindale, 1975). Kaolinite, dickite, nacrite, and halloysite can be differentiated from chlorite by comparisons of the 3.58-angstrom kaolin peak with the 3.54-angstrom chlorite peak (Biscaye, 1965), and from chlorite and the trioctahedral members of this group by intercalation with potassium acetate (Wada, 1965). pubs.usgs.gov /of/2001/of01-041/htmldocs/clays/kaogr.htm   (313 words)

KAOLINITE   (Site not responding. Last check: 2007-11-07) Kaolinite can also be formed by penetration of groundwater or hot water into large granite bodies, kaolinising the feldspar crystals before exposure at the surface. Kaolinite transported into a marine environment (for example near a delta) may be buried within muddy sediment and may react with soluble iron in the pore water. Kaolinite is an important geological resource, in a high purity form it is used in medicines and tooth-pastes, as the whitening agent in some paints, as the print surface in paper, and to produce high temperature furnace bricks for the metals industries. www.brookes.ac.uk /geology/sedmins/kaolinit.html   (520 words)

PIMA Applications The Kaolinite Group of minerals includes kaolinite, halloysite, dickite, nacrite, "endellite", allophane, and additional commercial clay types such as ball clay and flint clay. Kaolinite is a 1:1 phyllosilicate and an acid pH mineral. A commonly observed phenomenon in mineral deposits with illitic, sericite or phyllic alteration is the kaolinitization of the illite/mica. www.pimausa.com /clay_min.html   (2124 words)

Raman and Infrared Spectroscopic Study of the Modification of Kaolinite Surfaces by Intercalation with Organic Molecules   (Site not responding. Last check: 2007-11-07) In this article, the intercalation of a number of organic molecules in kaolinite, a 1:1 clay mineral which is generally assumed not to swell, is described along with the influence of these molecules on the clay internal and external surfaces. Kaolins (a group of 1:1 clay minerals including kaolinite, dickite, nacrite, and halloysite or hydrated high defect kaolinite) have quite often been qualified as clays that are not capable of expansion, in contrast to smectites (a group of swellable 2:1 clay minerals). The infrared and Raman spectra of pure kaolinite are well known ((8), (9)), and changes in these spectra during intercalation have to be interpreted as being caused by changes in the bonds between the clay layers itself and between the clay layers and the guest molecules. www.dekker.com /sdek/22740915-25165586/abstract~db=enc~content=a713562340~words=   (916 words)

Effect of stirring on kaolinite dissolution Experiments were carried out measuring kaolinite dissolution rates using stirred and non-stirred flow-through reactors at pH 2 to 4 and temperatures of 25°, 50° and 70°C. The results show an increase of kaolinite dissolution rate with increasing stirring speed. The effect of stirring speed on kaolinite dissolution rate is higher at 25°C than at 50° and 70°C and at pH 4 than at pH 2 and 3. The latter were calculated by dividing the dissolution rate of kaolinite KGDB obtained by Ganor et al. www.bgu.ac.il /geol/ganor/papers/GCA_W0638/GCA_W0638.htm   (3444 words)

Example 6.-- Reaction-Path Calculations Kaolinite, muscovite, and microcline are allowed to precipitate if they become saturated, but they can not dissolve because they were given zero initial moles in the phase assemblage. In simulation A5, point C is calculated by allowing microcline to dissolve to a point where kaolinite is at saturation and is present in the phase assemblage, while gibbsite is at saturation, but not present in the phase assemblage. Assigning an initial amount of 1 mol to kaolinite in A5 and muscovite in A6 is arbitrary; the amount must be sufficient to reach equilibrium with the mineral. wwwbrr.cr.usgs.gov /projects/GWC_coupled/phreeqc.v1/html/phqc_57.htm   (1084 words)

THE CLAY GROUP The general structure of the kaolinite group is composed of silicate sheets (Si) bonded to aluminum oxide/hydroxide layers (Al) called gibbsite layers. Uses: In ceramics, as a filler for paint, rubber and plastics and the largest use is in the paper industry that uses kaolinite to produce a glossy paper such as is used in most magazines. The gibbsite layers of the kaolinite group can be replaced in this group by a similar layer that is analogous to the oxide brucite, (Mg The structure of this group is composed of silicate layers sandwiching a gibbsite (or brucite) layer in between, in an s-g-s stacking sequence. mineral.galleries.com /minerals/silicate/clays.htm#mont   (905 words)

Reevaluation of surface protonation data based on results of dissolution experiments – the kaolinite case study The aim of the present study is to compare available surface titration curves of kaolinite, to explain the differences between them, and to constrain their interpretation based on predictions of surface protonation that emerged from dissolution experiments. Each of these two curves started with an initial stage in which kaolinite suspension was equilibrated in a background electrolyte solution of 0.1M NaCl.   The kaolinite basal surfaces carry a negative permanent surface charge, which is attributed to substitution of Si by Al in the tetrahedral layer of the kaolinite and to isomorphic substitution in other clays that are present as contamination in the sample. www.bgu.ac.il /geol/ganor/papers/JCIS_652/JCIS652.htm   (2669 words)

Fixation of Lead Chloride on Kaolinite and Bentonite at Temperatures between 550 and 950 C   (Site not responding. Last check: 2007-11-07) The results revealed that dehydrated kaolinite (metakaolinite) had a moderate ability to fix lead chloride while fresh kaolinite showed a significantly increased fixation ability. It was seen that during dehydroxylation of kaolinite, part of the chloride was released in the form of hydrochloric acid. Chemically bound water in kaolinite appeared to dramatically promote its reaction with lead chloride. pubs.acs.org /cgi-bin/abstract.cgi/iecred/2000/39/i02/abs/ie9905097.html   (226 words)
