Versatile Molybdenum

Summary

Molybdenum, the metallic element which is the object of AMAX Inc. exploration activities at Mt. Emmons in Gunnison County, Colo., was discovered in 1778 by Carl Wilhelm Scheele, a Swedish scientist who earlier had been the first man to isolate oxygen, fluorine and chlorine. Its name was derived from the Greek word “molyb- dos,” which means “lead-like.” In its pure form, molyb- denum (pronounced mo-lyb'-den-um but often called “moly”), like lead, is gray in color and is heavier than iron. But there the comparison ends for — among other things — lead meits at 621 degrees Fahrenheit, while the melting point of molybdenum is 4,730 degrees Fahrenheit. That is but one of the properties which makes moly so versatile. Iron, by comparison, melts at 2,795 degrees Fahrenheit. Early Moly Uses A century passed before metallurgists found a use for moly. First, in 1894, the French developed tough armor plate by adding molybdenum to steel. German
