It is a silvery black solid that occurs as the mineral molybdenite, the principal ore for molybdenum.〔 Sebenik, Roger F. ''et al''. (2005) "Molybdenum and Molybdenum Compounds" in ''Ullmann's Encyclopedia of Chemical Technology''. Wiley-VCH, Weinheim. 〕 is relatively unreactive. It is unaffected by dilute acids and oxygen. In appearance and feel, molybdenum disulfide is similar to graphite. It is widely used as a solid lubricant because of its low friction properties and robustness. == Production == Molybdenite ore is processed by flotation to give relatively pure , the main contaminant being carbon. also arises by the thermal treatment of virtually all molybdenum compounds with hydrogen sulfide or elemental sulfur. It can also be produced by metathesis reactions from molybdenum pentachloride. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「molybdenum disulfide」の詳細全文を読む スポンサード リンク
