钼 (molybdenum) is a chemical element with the symbol Mo and atomic number 42. It is a silvery-white metal known for its high melting point and strength. Molybdenum is primarily used in steelmaking to enhance the strength and durability of steel alloys, making it essential in construction and manufacturing. In addition to its role in metallurgy,钼 is also important in various chemical processes. It is used as a catalyst in the production of hydrocarbons and in the creation of molybdenum disulfide, a lubricant. Its unique properties make it valuable in electronics and aerospace applications as well.
