Sintering, microstructure and properties of a beach sand sillimanite have been investigated. The effect of ZrO2 on the densification behaviour and properties of the aggregate was studied. It was found that ZrO2 addition slightly reduces the densification of the beach sand sillimanite. Thermo-mechanical properties of the aggregate at 1200 degrees C also deteriorates to a little extent, particularly at higher percentage of ZrO2. Scanning electron photomicrographs show that ZrO2 occupies both the intergranular and intergranular position of the mullite matrix. Mullite formed at 1600 degrees C is elongated in nature, which suggests densification occurs through liquid phase sintering.
