molybditen.

Brit.

/məˈlɪbdʌɪt/, U.S.

/məˈlɪbˌdaɪt/

Origin: A borrowing from German. Etymon: German Molybdit.

Etymology: < German Molybdit (A. Breithaupt 1858, in Berg- u. hüttenmännische Zeitschr. 17 125) < Molybd- (in Molybdän : see molybdena n.) + -it -ite suffix¹.Compare Hellenistic Greek μολυβδῖτις, classical Latin molybdītis (Pliny) a variety of litharge or lead oxide; also French molybdite mineral rock containing lead (1752), and similarly post-classical Latin molybdites:1727 P. Shaw & E. Chambers tr. H. Boerhaave New Method Chem. i. 134 Pyrites..is differently denominated, according to the seed or stamen of metal it contains: crysites, if gold; argites, if silver; chalcites, if copper; molybdites, if lead; siderites, if iron.

Mineralogy.

Molybdenum trioxide, crystallizing in the orthorhombic system and usually occurring as flat yellow needles and plates forming encrustations.
