Abstract

Summary A new mineral, akaganéite, has been found in limonite deposits and has been shown to be identical with synthetic β -FeOOH. It contains no chlorine. The micro-morphology of β -FeOOH as it occurs as akaganéite and as it is produced by a solid-state transformation from FeCl 2 .4H 2 O , by the hydrolysis of dilute FeCl 3 solutions, and by the hydrolysis of very concentrated FeCl 3 a solutions, has been studied, chiefly by electron microscopy and diffraction. Some modes of colloidal association of the particles of β -FeOOH are described.
