Ball Clay
Ball clay, like china clay, is a variety of kaolin. It differs from china clay in having a higher plasticity and less refractoriness. In chemical composition, ball and china clays do not differ greatly except that the former contains a larger proportion of silica. Its name is derived from the practice of removing it in the form of ball-like ...

Basics of Clay Minerals and Their Characteristic Properties
The formation of clay minerals is due to the chemical weathering of rock [9, 10]. The chemical and structural composition of clay minerals is found to be similar to the primary minerals which originate from the crust of earth mainly from igneous or metamorphic rocks. Transformations may occur in ambient conditions.

Clay minerals are very small, usually less than 4 µm in diameter, and have net negative sur-face charge (Brindley and Brown, 1980). Their high surface area and negative charge, providing large reaction surface and ion-exchange capacity, allow clay minerals to track relatively subtle changes in flu-id chemical composition.

Clay Minerals
Ball clays and kaolin are both primarily kaolinite in most cases. A small amount to significant fractions of quartz are also found. If the chemical composition of pure kaolinite powder (39.5% alumina, 46.5% silica, 14% water) is compared to the composition of a typical kaolin or ball clay, the presence of silica is apparent.

Ball Clay (or plastic clays), is a kaolinitic mineral clay and a member of the phyllosilicate group of minerals. It occurs generally as an aluminium silicate comprising weathered forms of quartz, mica and kaolinite. Although similar in chemical composition, BALL CLAY is not as common as kaolin and differs substantially in physical characteristics.

Understanding the Differences: Ball Clay vs. Kaolin Clay
Ball clay has a higher density due to its smaller particle size, resulting in a denser material. Kaolin clay, with its larger particles, has a lower density. Chemical composition is an important aspect to consider in ceramics production. Ball clay consists of a combination of minerals, primarily composed of kaolinite, mica, and quartz.
