Preparation of α-alumina nanoparticles via vapor-phase hydrolysis of AlCl3
Source abstract
Abstract
A novel alumina precursor, represented as AlO x Cl y (OH) z , was prepared in a batch reactor through a vapor-phase hydrolysis of AlCl 3 at 200 °C for 1 min. The precursor particles were spherical and distributed in the size range of 30 to 200 nm, giving a number-average diameter of 70 nm. The precursor particles were calcined at 1200 °C for 6 h to obtain α-alumina nearly 100% in α-transformation degree. The weight loss upon calcination was 40%, comparable to 35% of Al(OH) 3 . The surface-area equivalent diameter of the obtained α-alumina particles was calculated to be 35 nm.
