... a series of reactors for making titanium. A Bureau publication in 1946 described a Kroll unit capable of making 7 kg (15 lb) batches of good-quality titanium powder by magnesium reduction, followed by acid leaching to remove the excess magnesium and MgCl 2 ( Fig. 1.1 ). In 1949, the Bureau reported...
