What is the difference between porcelain stone and kaolinite?
It is the name for the two rock albite diorite or albitite, weathered soil known as porcelain clay, porcelain stone ceramics containing AI2O316% SiO272%. porcelain stone as ceramic raw materials can be made of porcelain alone, can also be used as ingredients instead of potassium feldspar porcelain stone. Superfine grinding and surface modification of the glaze made of deep processing and fine powder materials and composite materials, widely used in ceramics, plastics, rubber, paper and other fields.
Belong to the kaolinite clay mineral, its chemical composition is Al4[Si4O10] (OH) 8, layered silicate mineral crystal belongs to triclinic. Three were dispersed cryptocrystalline, powder, loose bulk collection of white or light gray, light green, yellow, red and other colors, white streak, earthy luster, Mohs hardness of 2-2.5, the proportion of 2.6-2.63. absorbent, and water has plasticity, sticky tongue, dry clods with rough feeling.
Kaolinite English name for kaolinite, is a product of feldspar and other natural silicate mineral alteration, is a hydrous aluminum silicate. It also includes dickite, nacrite and halloysite and similar components but amorphous allophane, so they belong to the type of clay minerals called a [1], they always exist in the extreme small microcrystalline or cryptocrystalline state, and that massive or earthy aggregate. Kaolinite or dense or loose bulk, usually white, beige. If the impurities are kaolinite by weathering or deposition into kaolin, kaolin and is made of ceramic raw materials. In addition, kaolin can be as chemical materials, refractory materials, building materials and so on, and is widely used. Chinese Jiangxi Jingdezhen has a Gaoling village, here is rich in kaolin, hence the name. At the end of the Ming Dynasty in Jingdezhen kaolin mining village of the mine, after Richthofen, a German geologist, introduced Kaolin into the world of mineralogy according to the transliteration of kaolin
Kaolinite is the main mineral composition of kaolin, weathering crust is common in magmatite and metamorphic rocks. Chinese famous origin are Jiangxi Jingdezhen, Jiangsu kaolinite Suzhou, Hebei Tangshan, Hunan and Liling. The rest of the world famous origin of British Cornwall and Devon, France, the United States of Georgia Irie. Kaolinite is the main raw material for ceramics in other industries, it is also widely used.
