Refractoriness: High ...
Ball clay is a big part of porcelain since it can help with keeping everything together. We'll dive further into the benefits of ball clay, but ball clay is used in almost every type of ceramic materials, and because it's a big demand, the sales of this being exported around the globe are increasing, and it's a major product of the UK.
May 19, 2006· Polychlorinated dibenzo-p-dioxins (PCDDs) of high concentrations in a ball clay deposit from the Mississippi Embayment were found to be consistent with a natural abiotic and non-pyrogenic origin by investigation with bulk radiocarbon analysis, compound-specific chlorine isotope analysis (CSIA-δ37Cl) of octachlorodibenzo-p-dioxin (OCDD), and black carbon (BC) analysis.

An increase in the porosity of a fire clay was accompanied by a corresponding decrease in expansion between 15° and 1000°C until a porosity of 50% was attained. Further increase in porosity produced very little change in the expansion. No irregularities in expansion were shown by magnesia brick, carborundum, or alumina bonded with 10% of ball ...

Mar 02, 2014· Kaolinite grades Clays are categorized into six groups: 1) Kaolin or china clay: white, claylike material composed mainly of kaolinite industrial applications: paper coating and filling, refractories, fiberglass and insulation, rubber, paint, ceramics, and chemicals 2)Ball clay: kaolin with small amount of impurities industrial application ...
Jan 01, 2008· Chlorine isotope analysis of OCDD was carried out in ball clay recently (Holmstrand et al., 2006), and the chlorine isotope composition of OCDD suggested non-biologic origin of OCDD rather than an origin via biotic chlorination by perchlorooxidase enzymes. The chlorine isotope and black carbon results indicated abiotic and non-pyrogenic origin ...

Ball clay is an extremely rare mineral found in very few places around the world. Its name dates back to the early methods of mining when specialized hand tools were used to extract the clay in rough cube shapes of about 30 cm. As the corners were knocked through handling and storage these cubes became rounded and 'ball' shaped.
Polychlorinated dibenzo-p-dioxins (PCDDs) of high concentrations in a ball clay deposit from the Mississippi Embayment were found to be consistent with a natural abiotic and non-pyrogenic origin by investigation with bulk radiocarbon analysis, compound-specific chlorine isotope analysis (CSIA-δ37Cl) of octachlorodibenzo-p-dioxin (OCDD), and black carbon (BC) analysis.
