148 AIRCRAFT ENGINEERIN G April, 1939 Japanes e Plans Compared with the Industries Already Existing or Developing in Other Countries By Dr. J. Rubinfield* Institut e for Physical and Chemical Research, URING the second half of the year 1938 Aluminium Co. of America itself may put the magnesium licences it held for some years i.e., the manufacture of magnesium from Japanese efforts to achieve great from the German I.G. Farbenindustrie to brine. Large discoveries of magnesite in producing power in aluminium and magnesium have been very intense. Curiously practical account. In England also the simul Manchuria and the active assistance given by enough, relatively better results are anticipated taneous increase of both aluminium and mag th e laboratories of the South Manchuria for the latter, in spite of the greater technical nesium production is very evident from the Railways Co. have, however, led to the large- difficulties in the process of the production of fact that at the same time as a new aluminium scale practice of chlorinating magnesite to magnesium chloride and subsequent recovery pure magnesium than for aluminium.

The aggregate initial capa example of a long scries of countries taking up magnesium production from domestic dolo cities of the last-named eight newcomers is to and intensifying both lines. In Germany the mite by thermo-chemical reduction, which is amoun t to 7,500 metric tons a year, to be aluminium industry underwent an enlargement said to be considerably cheaper than the usual increased subsequently to 14,800 tons, while of its capacities as compared with tha t obtaining electrolysis of the chloride, and, moreover, the th e combined capacities of the first mentioned in the year 1932 by sixfold (while the actual Montecatini group itself is embarking upon three older established producers are to attain outpu t is ninefold) during 1938. At the same magnesium production. 2,700 tons at least within a short time. So time the powerful I.G. Farbenindustrie has far, the Nippon Electric Power Co.
