The aluminium retention in the lungs in rats and hamsters exposed to fume was much greater than when exposed to powder. However, due to the presence of contaminants (iron(III) chloride), it acquires a yellowish colour. When the temperature is further increased to about 400°C, aluminium oxide is formed from the hydroxide. Here Al3+ ions are occupying octahedral voids and Cl- ions forms a space lattice. The colour of aluminium chloride is white, but often it is contaminated with iron trichloride, which makes it yellow.
