Return of the Carbon Age CARBON... one of Nature's old est and most plentiful materials ... is making possible some of industry's newest achievements. In the chemical industry, massive black towers of carbon ... erected in incredibly short periods of time . speed the delivery of vital acids. The all-carhon electrostatic precipitator S. . built of carbon from the bottom tothetopofthestack...isnowan actuality. Such towers can be erected in as little as a week's time! Staunchly imn une to corrosion and thermal shock, they should last indefinitely. 'l'oday ... due to basic and ap plied research into the proper ties of carbon and graphite ... it is possible to obtain these black, wsonder-working materials in such a variety of forms-blocks, bricks, beams, tubes, pipes, and fittings . . . een valves and pumps . . . that almost any size or shape of structure can be built from them. For making tight joints, which give the strue ture uniform properties throughout, special carbon- and graphite-base cements have been developed. Undisturbed by the torture of heat, carbon is also a "must" in the metallurgical industry. Car bon cannothe melted ... will not soften . . . and has remarkable dimensional stability even at incandescent heat. In addition, it will not flake off and hot metal will not stick to it. That is why it is ideal for such uses as molds, cores, and plugs . . . for the lining of furnaces...and for sampling-dippers. Because electric-furnace graph ite conducts heat even better than most metals, it is becoming increasingly important in the manufacture of heat exchangers for the processing of corrosive liquids and gases. These new uses for carbon and graphite S. added to the almost interminable list of uses that existed before . . . make this era truly a carbon age. Your inquiries are cor dially invited. The strides made in the development of struc tural carbon, and in the uses of other carbon and graphite products, are greatly facilitated by the technical assistance of other Units of I nion Carbide and Carbon Corporation in clidiing The Linde Air Iroducts Company, (:arbide and Carbon Chemicals Corporation, Electro MetallurgicalCompany, laynesStellite Company, and Union Carbide and Carbon Research Laboratories, Inc. - all of which col laborate with National Carbon Company in re search into the properties and applications of carbon and graphite.
