Synthesis of Aluminium Titanate Ceramics from Waste Sludge of Aluminium Factory

Abstract:

Aluminium titanate was synthesized using waste aluminium sludge and chemical pure TiO2 powder as raw materials. Effect of different compositions on crystal structure and contents of target product was discussed. XRD results showed that four crystal phases, aluminium titanate, perovskite, rutile and aluminum oxide, are formed in the sintered samples. The content of aluminium titanate increases first and then decreases with the decrease of the content of waste aluminum sludge. When the content of the sludge is 65.52wt%, the content of aluminium titanate reaches the maximum of 86.1wt%.
