Product description
Calcined kaolin (also called metakaolin) is a powdered white non-plastic material.Calcination makes the powder whiter and more chemically inert. That makes it useful in a wide variety of products and industries. 
Calcined kaolin has other uses in ceramics. It is refractory and softens at about cone 35. It is thus useful in refractory castables and furniture, thermal insulation bodies, low expansion bodies, permeable ceramic compositions, and investment casting. Calcined kaolins are also useful in tuning the shrinkage and plasticity of slips (engobes) which are applied to wet, leather hard or dry ware. Engobes contain higher clay percentages than glazes and it is more important to control their drying shrinkage. Thus they can be substituted for part of the raw kaolin to tune drying while maintaining fired properties.
