Wulfenite is a lead molybdate mineral with the formula PbMoO4. It can be most often found as thin tabular crystals with a bright orange-red to yellow-orange color, sometimes brown, although the color can be highly variable. In its yellow form it is sometimes called "yellow lead ore". It crystallizes in the tetragonal … See more Wulfenite was first described in 1845 for an occurrence in Bad Bleiberg, Carinthia, Austria. It was named for Franz Xavier von Wulfen (1728–1805), an Austrian mineralogist. It occurs as a … See more Wulfenite crystallizes in the tetragonal system and possesses nearly equal axial ratios; as a result, it is considered to be crystallographically similar to scheelite(CaWO4). Wulfenite is classed by a pyramidal-hemihedral (tetragonal dipyramidal) … See more Wulfenite has been shown to form synthetically through the sintering of molybdite with cerussite as well as that of molybdite with lead … See more • List of minerals named after people • Tungsten • Stolzite See more The crystals of wulfenite are usually more tabular and thinner than those of scheelite, however, the more pyramidal and prismatic crystals show distinct hemimorphism. See more The heat capacity, entropy and enthalpy of wulfenite were determined taking into consideration the existence of solid solutions and the … See more Pure wulfenite is colorless, but most all samples display colors ranging from a creamy yellow to a sharp, intense red. Some samples even display blues, browns, and blacks. The yellow and red coloration of wulfenites is caused by small traces of chromium. Others … See more
