physicochemical properties of kaolin powder

  • Physicochemical Problems of Mineral Processing

    Coal-series kaolin transformed into irregular and amorphous metakaolin with excellent properties as calcined at °C which attributed to the dehydroxylation of kaolinite and combustion of carbon/organic matter. Calcined kaolin eliminated activity ascribed to the recrystallization into mullite when calcination temperature was over 1000 °C.
