Kaolin | Article about kaolin by The Free Dictionary

Kaolins are formed through the weathering of various magmatic, feldspathic rocks (primarily low-ferriferous granites; more rarely, argillaceous sediments or arkoses called primary kaolins). They are also formed through the rewashing of these rocks, the kaolins then being redeposited in sedimentary (chiefly sandy) strata (secondary kaolins, or

Kaolin Pennsylvania State University

Secondary deposits are laid down as sediments, usually in fresh water, far from the place of origin. Various types of secondary kaolins may be termed ball clays, fireclays or flint clays depending on their properties or use (New South Wales DMR, 1998). Replacement. The replacement range for calcined kaolinite depends on the reactivity of the

Kaolin an overview | ScienceDirect Topics

Secondary kaolins tend to be of lower aspect ratio. But some Brazilian examples are exceptions to this rule. Kaolin can be used as a filler in both acid and alkaline papermaking because of its chemical composition. The brightness of regular filler kaolin is distinctly lower than most calcium carbonate-based fillers. Because of this, kaolin has

Kaolinite Wikipedia

Kaolinite (/ ˈ k eɪ ə l ɪ n aɪ t /) is a clay mineral, part of the group of industrial minerals with the chemical composition Al 2 Si 2 O 5 4.It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO 4) linked through oxygen atoms to one octahedral sheet of alumina (AlO 6) octahedra. Rocks that are rich in kaolinite are known as kaolin / ˈ k eɪ ə l ɪ n / or china clay.

Sancai Wikipedia

Sancai wares were made in north China using white and buff-firing secondary kaolins and fire clays. Sancai follows the development of green-glazed pottery dating back to the Han period (25-220 AD); the brown glaze was also known to the Han, but they only very rarely mixed the two in a single piece. After the Han the use of these glazes almost disappears for some four hundred years, which has

Natural Kaolins also classified in two main groups, primary and secondary as a raw material. Primary kaolins are found naturally where they exist. Secondary Kaolins are washed and deposited away from primary kaolins. Lower impurities and high brightness are the main parameters to differentiate secondary kaolins from primary kaolins.
