TOHO Titanium Co. erected 20 T per month plant of titanium sponge in 1953 and developed it to 150 T per month within 4 years.But the price of titanium has fallen down year by year and the demand for it decreased since 1957. So we have endeavoured cut down the production cost.The methods of rationalization are as follows:1) Improvement of the operation of chlorinato- and recovery of TiO2 from its waste.2) Simplification of TiCl4 purification.3) Diminution of magnesiuem losses at the reduction process and others.4) The reduction of production cost of magnesium by the rationalization of its electrolytic plant.With these above and other several improvements. we have been able to reduce the production cost of titanium sponge about 20% during these 4 years.
