摘要： The present invention relates to calcined kaolin products, their production, and use. More specifically, the invention relates to calcined kaolin-containing products having a median diameter particle size of from about 0.5 &mgr;m to about 10 &mgr;m, and a multimodal particle size distribution defined herein. The calcined kaolin products of the invention possess a combination of physical properties and applied properties not previously seen together in calcined kaolin pigments. The products according to the invention find use as flattening (or matting) agents, and as fillers or extenders in paint and coating compositions. More generally, the inventive products may be used wherever calcined kaolins are used.

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： The present invention relates to calcined kaolins having optimal whiteness and brightness properties. The calcined kaolins can comprise metakaolin, fully calcined kaolin, or flash calcined kaolin. The kaolin can be calcined from hydrous kaolin that has been subjected to enhanced magnetic separation. The resulting calcined kaolin can have a whiteness defined by a Hunter lab coordinate L value of at least about (96). The calcined kaolin can also have a brightness of at least about (90), as measured by a Technibrite TB-1C instrument. The present invention also relates to methods of preparing calcined kaolins. The present invention also relates to paints, polymers, coatings, ceramics, paper, and cementitious products comprising these calcined kaolins.
