摘要:
Disclosed herein are compositions comprising novel delaminated kaolins having a large particle size and low levels of alkali metal oxides. Methods of making the disclosed delaminated kaolin by calcining hydrous kaolin are described. Applications using the disclosed compositions in preparing catalyst substrates, paints, coatings, sealants, cementitious products, ceramics, rubbers, polymers and other compositions are also described.
摘要:
Disclosed herein are inorgano-neutralized calcined kaolin comprising calcined kaolin treated with at least one basic inorganic compound, a composition comprising the inorgano-neutralized calcined, and use of the inorgano-neutralized calcined kaolin in silicone rubber formulation. Further disclosed herein are a method of making the inorgano-neutralized calcined kaolin and a method of making a silicone rubber formulation comprising the inorgano-neutralized calcined kaolin.

摘要:
The present invention relates to calcined kaolin having an unusually narrow particle size distribution. The calcined kaolin can have a particle size distribution wherein: (I). The calcined kaolin may be prepared from a hydrous kaolin having a particle size distribution, wherein: (II). The calcined kaolin can be used in many applications, such as paint and coating compositions for paper or paper board, and more generally, the inventive products may be used wherever calcined kaolins are used.
