Kaolinite is a soft, earthy, usually white, mineral (dioctahedral phyllosilicate clay), produced by the chemical weathering of aluminium silicate minerals like feldspar. It has a low shrink–swell capacity and a low cation-exchange capacity (1–15 meq/100 g).

2023年4月23日 · Kaolinite is a clay mineral with chemical composition Al2Si2O5 (OH)4. It is an important industrial mineral. Rocks rich in kaolinite are called kaolin. Kaolinite, common group of clay minerals that are hydrated aluminum silicates; …

Kaolinite can have a lot of layer stacking variation, from highly ordered to highly disordered, while dickite and nacrite are effectively differently ordered polytypes. Poorly crystalline kaolinite is typical of low grade sediments, especially non-marine, while dickite and nacrite form at higher temperature, including many hydrothermal deposits.

高岭石(kaolinite) 亦称“高岭土”、“瓷土”。一种黏土矿物。因首先在江西景德镇附近的高岭村发现而得名。由长石、普通辉石等铝硅酸盐类矿物在风化过程中形成。

高岭土 （英語： Kaolinite），又稱 觀音土 、 白鱔泥 、 膨土岩 、 斑脱石 、 甘土 、 皂土 、 陶土 、 瓷土 、 白泥，礦物學中以 高岭石 稱之，是一種含 鋁 的 页矽酸鹽礦物，呈白色軟泥狀，颗粒细腻，狀似面粉。 其化学成分相当稳定，被誉为“万能石”。 為製造 瓷器 和 陶器 的主要原料。 英語名稱「Kaolinite」源自於中國 江西省 景德鎮 附近的一個村莊名稱。 2 · 2H 2 O。 [5] 高岭土主要在地表之下，其质地和成分的不同可以直接影响到陶和瓷在窑中的变化，所以优质的高岭土可以 …

2016年10月1日 · Throughout this paper the term kaolin is exclusively used to describe a rock, soil or ore irrespective of its origin, provided that kaolinite-group phyllosilicates prevail over their associates. If a mineralogical issue, e.g., crystallinity or morphology is addressed, the specific technical terms in use for the kaolinite-group minerals are ...

2016年10月1日 · Kaolin, although a rather homogeneous rock, and due to its dull outward appearance not high up on the agenda of mineral enthusiasts and rockhounds, has attracted mining and ceramic engineers involved in the manufacture of chinaware, and economic geologists dealing with non-metallic deposits.

From the industrial point of view, kaolin is a clayey rock consisting mostly of kaolinite. Kaolinite is one of the most common minerals on Earth and can be easily identified by its almost pure white color, fine particle size (∼1–2 µm), non-toxicity, very low abrasiveness, and chemical stability.

Kaolinite is a clay mineral, with a soft consistency and earthy texture. It is easily broken and can be molded or shaped, especially when wet. Kaolinite is a lackluster and uninteresting mineral on its own, but it occasionally forms interesting pseudomorph s, especially after feldspar s.

Compared with other clay minerals, kaolinite is chemically and structurally simple. It is described as a 1:1 or TO clay mineral because its crystals consist of stacked TO layers. Each TO layer consists of a tetrahedral (T) sheet composed of silicon and oxygen ions bonded to an octahedral (O) sheet composed of oxygen, aluminum, and hydroxyl ions.
