What is the structure of kaolinite?
Kaolinite is a clay mineral of chemical formula Al2O3 2SiO2·2H2O that has a structure of 1:1 uncharged dioctahedral layer where each layer consists of single silica tetrahedral sheet and single alumina octahedral sheet [123,124].
What is Palygorskite made up of?
Palygorskite is a clay mineral characterized by a microfibrous morphology, low surface charge, high magnesium content, and high specific surface area (Singer, 2002). Palygorskite-containing soils occur almost exclusively in arid and semi-arid areas of the world.

What is the difference between kaolin and kaolinite?
is that kaolinite is (mineralogy) a common hydrous aluminosilicate mineral found in sediments, soils and sedimentary rocks, al]]2si2o5([[hydroxide|oh)4; one of the kaolin group of minerals while kaolin is a fine clay, rich in kaolinite, used in ceramics, paper-making, etc.
What shape is kaolinite?
Kaolinite, nacrite, and dickite occur as minute, sometimes elongated, hexagonal plates in compact or granular masses and in micalike piles. They are natural alteration products of feldspars, feldspathoids, and other silicates.
What elements are in kaolinite?
Kaolinite is a mineral that forms largely by soil–forming processes, most commonly the chemical breakdown of feldspars , accompanied by leaching of elements such as calcium (Ca) , sodium (Na) , and potassium (K) , to form the aluminum (Al) –rich product.
Is kaolinite a cleavage or fracture?
Cleavage is perfect in one direction, basal. Fracture is earthy. Hardness is 1.5 – 2 (can leave marks on paper). Specific Gravity is 2.6 (average).
What is the luster of limonite?
silky
Hardness is 4-5.5, luster is silky or earthy, streak is yellowish brown, and specific gravity is 2.7-4.3. Much of the material formerly thought to be limonite now is known to be goethite, which is crystalline and has a definite chemical composition.
What is attapulgite made of?
Attapulgite is a naturally mined clay. It is a needle-like clay mineral composed of magnesium-aluminum silicate. Major deposits occur naturally in Georgia, USA.
