Talc (3MgO·4SiO₂·H₂O) has excellent mechanical properties, shock and abrasion resistance, good electrical and thermal shock resistance, softness, isolation, chemical activity, heat resistance and oil absorption properties. Aluminium titanate (Al₂TiO₅) exhibit extremely good thermal shock resistance and low thermal conductivity coupled with good chemical resistance in molten metals. In the present work, Aluminium titanate/talc ceramics composites with different percentages of Al₂TiO₅ was prepared using powder metallurgy techniques. The microstructural, mechanical and thermal properties were characterized using XRD, SEM, dilatometer and hardness. Thermal shock resistance behaviour under water quenching of the as-prepared ceramics was also evaluated. Results, revealed that the addition of aluminium titanate to talc matrix improves the properties of the aluminium titanate/talc ceramics.
