Effect of Tween‐80 on the Control of Particle Size and Shrinkage Properties of Nanoscale α‐Alumina Synthesized by Sol–Gel Processing

The concept of tailored interfaces has been applied to the synthesis of nanoscale α-Al 2 O 3 . Tween-80 (poly-oxyethylene(20) sorbitan monooleate, T-80) was used as a surface modifier in the sol-gel process for this purpose. High-resolution transmission electron microscopy study of the powder obtained with T-80 confirmed the particle size of α-Al 2 O 3 (∼55 nm) and morphology (spherical). The exothermic peak temperature in the differential thermal analysis was shifted to a lower temperature (∼917°C) when the powder was derived from a T-80 modifier content of 10 wt%. X-ray diffraction showed that the α-Al 2 O 3 phase was the major phase that existed in modifier-derived powder that was sintered at 1000°C. The experiments, based on linear shrinkage, indicated that the powder with T-80 (10 wt%) could be densified at a low temperature.
