Molybdenite is a mineral that contains the element molybdenum. The word is spelled /məˈlɪbdənaɪt/ in IPA phonetic transcription, which means that it is pronounced muh-LIB-duh-nite. The initial syllable is pronounced with a schwa sound, followed by the stress on the second syllable. The letters "-bden-" are pronounced as "bDEN" with the "d" sound linking with the "b". The final syllable is pronounced like "nite" as in "night". Molybdenite is used in the production of steel and other metal alloys.
Molybdenite is a noun that refers to a mineral composed mainly of molybdenum disulfide (MoS2). It typically occurs as a soft, lead-gray or black, crystalline substance and is one of the principal ores of molybdenum. Molybdenite possesses a metallic luster and a high density, making it easily distinguishable. Its name is derived from the element molybdenum, which in turn is named after the Greek word "molybdos," meaning "lead," due to its similar appearance.
This mineral is commonly found in hydrothermal veins or as a byproduct of copper and tungsten deposits. It often occurs in association with other sulfide minerals and can be used to determine the age of rocks through dating techniques like uranium-lead dating. Molybdenite is also known for its thermal and electrical conductivity, making it suitable for various industrial applications, particularly in the production of alloys and lubricants.
Historically, molybdenite has been used to create pigments, as well as in the manufacture of steel, electronic components, and certain types of glass. Its versatility and unique properties have made it an essential mineral in numerous industries and have contributed to its economic significance. Furthermore, molybdenite has gained attention in recent years due to its potential use in renewable energy technologies, such as solar cells and catalysts for fuel cells.
An ore found in various rocks, and in veins with tin and other ores, closely resembling in colour that of fresh-cut metallic lead.

The word "molybdenite" is derived from the element "molybdenum", which is a chemical element with the atomic number 42. The term "molybdenum" itself originates from the Greek word "molybdos", which means "lead". The addition of the suffix "-ite" indicates that molybdenite is a mineral, often composed of molybdenum sulfide.
