摘　　要：Andalusite rich schist until now has not been utilized to produce refractory. In this work, refractory materials were elaborated from alumina-silica geomaterials related to granitoids and their direct surrounding rocks （kaolin clay and andalusite fiche schist）. Characterization evolution on heating was investigated in a composition （80% kaolinitic clay, 20% andalusite rich schist）. The evolution of mullite was examined by SEM （scanning electron microscopy） and XRD （X-ray diffraction）. The thermal shock test showed that the refractory sample has a good thermal shock resistance.

关 键 词：Kaolin mullite alusite firing.
