/wool"feuh nuyt'/, n.a lead molybdate mineral, PbMoO4, occurring usually in tabular crystals, and varying in color from grayish to bright-yellow or red; yellow lead ore.[1840-50; named after F. X. von Wulfen (1728-1805), Austrian scientist; see -ITE1]
* * *▪ minerallead molybdate, PbMoO4, a minor source of molybdenum and the second most common molybdenum mineral. It occurs in the oxidized zone of lead and molybdenum deposits. Fine crystals have been found at Příbram, Czech Republic; Yuma County, Ariz., U.S.; and Mapimi, Durango, Mex. Other localities include Germany, Austria, Sardinia, and Australia.Wulfenite ordinarily crystallizes as thin, beveled, square plates that have a resinous to adamantine lustre, and they are yellow to orange in colour.
