Q: How to distinguish kaolin?: It is a used porcelain porcelain, also called white clay, commonly referred to as gaoling. The chemical formula for kaolin is Al2O3 (alumina) 2SiO2 (silica) 2H2O (water). That is to say, kaolinite is hydrous silicate. Secondly, kaolinite does not dissolve in water. Other than hydrofluoric acid, it can not be dissolved by other acids, which is one of its characteristics. To distinguish kaolinite, mineral analysis methods can also be used. In recent years, the rapid development of modern science and technology, the application of kaolin is more extensive, began extensive use of kaolin as new materials in some high-tech fields, and even nuclear reactor space aircraft and spacecraft components with high temperature porcelain, made of kaolin. kaolin

Q: How can we tell if there's kaolin in that hill?: It can be distinguished by its physical and chemical properties:Its characteristics: more non gloss, pure color, white and delicate, such as containing impurities can be gray, yellow, brown and other colors. According to the different causes of appearance is clod shape and dense state of loose rock block.

Q: What is the good or bad of kaolin to distinguish? What is its criterion?What percentage does it contain and what element does it contain?: Kaolin is a kind of soft clay mineral and two non clay mineral, which are mainly composed of kaolinite and sub group minerals. Kaolinite minerals are mainly composed of small tabular or tubular kaolinite minerals of less than 2 m, Al4 [Si4O10] (OH) 8. Because of its hydrous aluminosilicate chemical composition, layered structure and particle size, it has many special properties which are not available in general minerals. The extensive use of kaolin is inseparable from its excellent physical properties. Pure kaolin with high whiteness, soft and easy to disperse suspended in water, refractoriness physicochemical performance, good plasticity and high adhesion, excellent electrical insulation properties and the acid solution, good low cation exchange capacity, high.

Q: Is the kaolin used in Longquan celadon?: The modern Longquan celadon porcelain lot with kaolin, kaolin from Longquan, the local people also called Dehua mud, many are purchased from Fujian Dehua side, are characterized by the porcelain matrix transparent, good transparency, welcomed by the market.

Q: What kind of pottery does kaolin need?: To see the production of the product is the grade, senior tableware to senior kaolin, sanitary ware, building materials and ceramic products with low-grade kaolin on the line, in fact, ceramic raw materials, in addition to feldspar and quartz and other raw materials are more or less containing kaolin ingredients, so not to say only a kaolin ceramic material

Q: What's the difference between Ye Lashi and kaolin?: The content of Si in Ye Lashi is much higher than that of Al. The amount of burning loss is relatively small, and the linear shrinkage is much smaller than that of kaolin. When adding to the raw material, the sintering process can promote sintering.

Q: China clay, kaolin clay, three what is the difference? Is China clay is kaolin chemical elements of the three specific? What is the difference?: Also known as clay kaolin, clay is composed of metamorphic mica and feldspar.

Q: How to identify kaolin?: Washed out kaolin can produce many unexpected consequences when used in the deployment of other raw materials.

Q: Does the whiteness of washed kaolin mean natural whiteness or whiteness after calcination?: Whiteness difference is big, generally after light burning, kaolin whiteness will increase, and wash water will not significantly increase whiteness.
