• Halloysite - Wikipedia

    en.wikipedia.org/wiki/Halloysite Halloysite is an aluminosilicate clay mineral with the empirical formula Al 2 Si 2 O 5 (OH) 4.Its main constituents are oxygen (55.78%), silicon (21.76%), aluminium (20.90%), and hydrogen (1.56%). Halloysite typically forms by hydrothermal alteration of alumino-silicate minerals. It can occur intermixed with dickite, kaolinite, montmorillonite and other clay minerals.
  • Halloysite: Mineral information, data and localities.

    www.mindat.org/min-1808.html Halloysite-10Å is also known as "endellite" in European literature and considered to be a hydrated mineral - the "hydrated halloysite" of North American literature. "Metahalloysite" (= Halloysite-7Å) is dehydrated halloysite and characterised by a reduced interlayer spacing. Originally reported from Angleur, Liège, Liège Province, Belgium.

    www.imineralsinc.com/our-products/halloysite Uses. Halloysite has historically been used in the manufacture of porcelain, bone china, and fine china. In these applications the combination of the tubular shape in clay with low iron and titanium content produces ceramic ware with exceptional whiteness and translucency.

    www.sigmaaldrich.com/technical-documents/.../nanoclay-halloysite-nanotubes.html Halloysite, a naturally occurring aluminosilicate nanotube, has been undeservedly forgotten. Halloysite (Al 2 Si 2 O 5 (OH) 4 •2H 2 O) is a two-layered aluminosilicate, with a predominantly hollow tubular structure in the submicron range and chemically similar to kaolin 1,2.The neighboring alumina and silica layers, and their waters of hydration, curve and form multilayer tubes (Figure 1 ...
  • Halloysite and Kaolinite | Clays and Minerals

    www.claysandminerals.com/halloysite-and-kaolinite Halloysite loses its interlayer water very easily so it is often observed in a partly dehydrated state. In its fully hydrated form the formula is Al 2 Si 2 O 5 (OH) 4 -2H 2 O. Kaolinite is a very important industrial mineral, and halloysite is becoming increasingly important due mainly to its use in nanotechnology applications which take ...

    phantomplastics.com/functional-fillers/halloysite Halloysite has long been used and is a ideal because of high whiteness, which gives a translucent article once fired. The tubular shape helps prevent sag, although it can also increase shrinkage. Large amounts of halloysite are supplied into the Asian market from the New Zealand deposit. Reinforcement for plastics

  • Halloysite - an overview | ScienceDirect Topics

    www.sciencedirect.com/topics/earth-and-planetary-sciences/halloysite Halloysite possesses interesting adsorption properties and is capable for efficient removal of inorganic (eg, heavy metals) and organic (eg, dyes) contaminants. Its low cost and environmental friendliness are its main advantages over other adsorbents. The unique morphology of the clay mineral, which could be found in nature, makes it a ...
