Description

Iron compounds contained in typical Al2O3-SiO2 refractories were investigated by cross-section observation, micro spot composition analysis and micro spot X-ray diffraction. The morphology of iron compounds could be classified adjacent with pores system （type-A） and included in the aggregates system （type-B）. And the point of iron compounds in type-A was an aggregate composed of many particles. Fe2O3 and/or TiO2 were dispersed in the aggregate in type-B. The particles of iron compounds in type-A were identified as hematite. However, in the 1400 ℃（0.5h）-fired sample, the particles were identified as rutile and mullite. The Fe-components might have diffused after high temperature heat treatment.
