Abstract: Magnetite pigments are prepared from iron(II) salt solutions by a process in which the mean particle size can be brought to a value within the range from 0.06 to 0.5 mu m by means of a residence stage between the precipitation stage and the oxidation stage.

Abstract: The radiography equipment is designed to overcome the difficulties experienced when the source of radiation (10) is fixed and the pipe casts a shadow onto a fixed plate (12). The radiation source is fastened to a frame so that it can be scanned over the pipe and the plate may be held in a frame which permits scanning motions.

Abstract: Iron oxide black pigments having improved acid resistance are obtained by treating them in aqueous suspension for 30 minutes to 200 hours at pHs from 0.5 to 14 and temperatures from 20 to 100 DEG C. The pigments aftertreated in this way are suitable for the colouring of cosmetics, pharmaceuticals and foodstuffs.
