Ball Clay - Digitalfire

Ball clay is not a clay mineral in itself, but contains other minerals, primarily kaolinite (but also montmorillonite, halloysite, and illite). Mica and quartz are also present in substantial amounts (e.g. 10-20% for Tennessee ball clays). Ball clays are very plastic and much

To be able to estimate the probable fired properties of a given ball clay, it is not enough merely to know its chemical composition. It is also necessary to know how the various elements present are distributed as minerals - in other words, where the SiO 2 , Al 2 O 3 , Fe 2 O 3 and alkalis are known, the amount of each of these in combination as kaolinite, hydromuscovite and quartz must be established.

Kaolin Al2H4O9Si2 - PubChem

Clay minerals contain bentonite, kaolin, fuller's earth, etc. Six types of clays are mined in the United States: ball clay, bentonite, common clay, fire clay, fuller's earth, and kaolin. Mineral composition, plasticity, color, absorption qualities, firing characteristics, and clarification properties are a few of the characteristics used to distinguish between the different clay types.

2015-9-10  Clays are categorized into six groups by the U. S. Bureau Of Mines. The categories arekaolin, ball clay, fire clay, bentonite, fuller’s earth, and common clay and shale. Kaolin, or china clay,is defined as a white, claylike material composed mainly of kaolinite, which is a hydrated aluminumsilicate (Al2O32SiO22H2O), and other kaolin-group minerals. Kaolin has a wide variety of industrialapplications including paper coating and filling, refractories, fiberglass and insulation, rubber, paint,ceramics, and chemicals. Ball clay is a plastic, white-firing clay that is composed primarily ofkaolinite and is used mainly for bonding in ceramic ware, primarily dinnerware, floor and wall tile,pottery, and sanitary ware.
