The kaolin powder was calcined at 750 °C for 2 h under an air atmosphere in an electrically operated furnace. It was then dispersed in 6 M hydrochloric acid solution maintaining a solid/liquid ratio of 1:20 by mass. The acid activation process was carried out at 70 °C for 6 h with continuous stirring under reflux condition. The mixture of ...

The work reports a procedure for the synthesis of γ-alumina from the Iraqi kaolin. Kaolin was transformed to metakaolin by calcination at 750 °C for 45 minute. γ-alumina powder was synthesized through extracting alumina from metakaolin via H2SO4 treatment and precipitation by ethanol, which produces aluminum sulfate of 99% purity.

1. Introduction. Kaolin is a white-brown powdery clay mineral. It has the main constituent of kaolinite of a hydrous aluminum silicate (Al 2 O 3.2SiO 2.2H 2 O) with a single tetrahedral silicate layer linked via oxygen molecules to a single alumina octahedral layer. The most common auxiliary minerals found with kaolin are maternal rocks such as …
