Effect of Properties of Calcined Microspheres of Kaolin on. · Fichier PDF
kaolin. Aqueous slurry of fine kaolin clay was prepared. The spray-dried slurry was used to obtain the precursor microspheres with particle sizes 40-80 mesh. The precursor microspheres were divided into two parts. One of them was calcined at a temperature above the characteristic exotherm of kaolin to produce type A microspheres(CMA). The other was
