The DuPont Company's new non-electrolytic hydrogen peroxide plant at Memphis, TN as seen during nighttime operation. The peroxide made here is shipped to textile and pulp mills in the southern area where it is used for bleaching. The chemical is also used in the rubber industry and in the synthesis of many organic and inorganic compounds. Sodium cyanide, another basic industrial chemical which makes an essential contribution to a number of vital products, is manufactured in a separate unit at the plant.
At the new DuPont Metals Center in Baltimore this 2,000 ton high speed forge press and argon muffle furnace provide for rapid forging of refractory metals. Billets can be heated to 2500 degrees Fahrenheit and contamination is minimized by the in process heating and rapid forging features of the press. The big forge press, which is operated from the console on the left, has a 40 inch maximum stroke and a power stroke speed of 150 inches per minute. The operations at the center where production of columbium metal and columbium alloys was just announced, are supported by the company's continuous research program which seeks new fundamental information on refractory metals. These new metals can stand the tremendous heat that is required of space age hardware.
