摘要：

Sintering behavior of Al2TiO5 without and with various additives and the thermal properties of the sintered material-thermal expansion and decomposition-were investigated. The precursors of Al2TiO5 powders were prepared by homogeneous precipitation and coprecipitation. Sintering of pure Al2TiO5 gave a fine grained-structure at 1300 degrees C, but resulted in large-grained and cracked microstructures at 1400 and 1500 degrees C. Addition of ZrO2 or BaO gave fine-grained microstructures with a small increase in thermal expansion. Addition of ZrO2, BaO or ZrSiO4, especially ZrSiO4, was effective in suppressing the thermal decomposition of Al2TiO5 at 1100 degrees C. (C) 1999 Elsevier Science Ltd and Techna S.r.l.
