1. Introduction. Ball clays have been increasingly utilized in the ceramic production to the point that the tilemaking industry turned to be the major end user, in particular in porcelain stoneware tiles (Sánchez et al., 2010, Dondi et al., 2014).Ball clay is defined as "fine-grained, highly plastic, mainly kaolinitic clay, the higher grades of which fire to a near white color in …
Feldspar has different chemical formulas each depending on its composition. The specific chemical formula is KAlSi 3 O 8 – NaAlSi 3 O 8 – CaAl 2 Si 2 O 8. The minerals are chemically alert and have a stable pH value.
Our range of Ball Clay is high on demand in the market. It is a highly plastic variety of clay of kaolin group. The high plasticity in ball clay is attributed to its particles being very fine grained. The pyrometric cone equivalent of ball clay hardly exceeds 33. Over 85 % of the particle sizes present in ball clay are less in diameter.
Ball Clay: Containing high levels of kaolinite along with other minerals like quartz (SiO₂) and mica, ball clay is highly plastic and workable. It is often used in blends to enhance the plasticity and workability of other clays. ... By understanding the chemical composition and properties of clay, potters and material scientists can ...

The ball clay:kaolin mix can be altered to change body plasticity without significantly affecting the maturing temperature. In North America, most commercial ball clays are mined in the southeastern US. Ball clay deposits are common and were laid by the action of slow moving water with an acidity that tended to flocculate and settle the clay.
The term "ball clay" originated from an early English mining practice of rolling the highly plastic clay into balls weighing 30–50 lb. Ball clay is used primarily in the ceramic industry for making such items as pottery, dinnerware, stoneware, and sanitary ware (e.g. Andreola et al., 2009).Ball clay is composed of poorly crystalline kaolinite with small amounts of illite, and (or) …
On the other hand, Table 2 also shows the ball clay chemical composition. The ball clay powder comprises silica (SiO 2) and alumina (Al 2 O 3), which corresponds to approximately 84%. The high loss of ignition (10.69%) is due to the presence of organic matter, hydroxides, and clay minerals.

Chemical composition and particle size are two useful indicators in choosing a replacement material. Always look for similarities in both when trying to substitute one material for another. Ask the ceramics supplier for a chemical analysis …
The chemical composition and structure changes before and after the activation of the clay were characterized by X-ray fluorescence, X-Ray Diffraction and Fourier transform infrared spectroscopy.
Porcelain tiles are vitreous ceramic products made of clay (kaolin and ball clay), feldspar and sand. The industrial production of these tiles consists of milling and homogenization, uniaxial pressing at 40–50 MPa and fast firing at 1180–1220 °C [1, 2].Porcelain tiles are known to have a high flexural strength of greater than 35 ± 2 MPa, and low water absorption (<0.5%) …
Ball clay commonly consists of 20-80% kaolinite, 10-25% mica & 6-65% quartz. Ball clay and china clay differ only in the degree of plasticity.
