摘要：
Disclosed herein are compositions comprising novel calcined kaolins having a large particle size and low levels of alkali and alkali earth metal oxides. Methods of making the disclosed calcined 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.
