    摘要： The present invention relates to coarse calcined kaolin slurries having a high solids content. The invention also relates to methods of making such slurries. The resulting slurries can have a solids content of at least about 58% by weight wherein at least about 40% by weight of the calcined kaolin particles has a particle size of at least about 1 μm. The slurries can be stabilized where the solids show little settling from suspension. The slurries have many uses, including fillers or extenders in paint and coating compositions for paper or paper board. More generally, the inventive products may be used wherever calcined kaolins are used. The present invention also related to coarse calcined kaolin slurries having a multimodal particle size distribution and a high solids content.

    摘要： A method of method of making a formed ceramic body, comprising casting or jiggering a composition comprising a mullite-rich calcined kaolin obtained from a hydrous kaolin. Also provided is a method of modifying/increasing the casting rate of a formed body formulation comprising hydrous kaolin, the method comprising substituting at least 10% of the hydrous kaolin in the formulation with a mullite-rich calcined kaolin. Also provided is a ceramic body filter cake comprising a mullite-rich calcined kaolin, wherein the mullite-rich calcined kaolin is obtained from a hydrous kaolin and a method of modifying/increasing the filtration rate of a ceramic body filter cake comprising hydrous kaolin, the method comprising substituting at least 10% of the hydrous kaolin in the ceramic body filter cake with a mullite-rich partially calcined kaolin. Also provided are dried greenware products and final ware products comprising a mullite-rich calcined kaolin, wherein the mullite-rich calcined kaolin is obtained from a hydrous kaolin.
