Chemical properties of the element molybdenum

Reaction with oxygen: Molybdenum reacts with oxygen at high temperature to form molybdenum oxide (MoO3). Molybdenum oxide is a yellow solid with good catalytic and adsorption properties, and is widely used in the fields of chemistry, metallurgy and environmental protection.

Reaction with non-metallic elements: Molybdenum can react with many non-metallic elements to form compounds. For example, it reacts with nitrogen to form molybdenum trinitride (MoN), a very hard material commonly used in coatings and metal cutting tools, and with sulphur to form molybdenum sulphide (MoS2), a common lubricant and solid lubricant film material.

Reaction with acids and bases: Molybdenum has good corrosion resistance and can withstand a wide range of acids and bases at room temperature. However, in the presence of molybdenum oxide, it can be corroded by concentrated nitric acid and hot concentrated sulfuric acid.

Formation of complexes: Molybdenum can form a variety of complexes, usually in the +4 and +6 valence forms. These complexes have a wide range of applications, such as catalysts, molybdenum enzymes in biology and dyes in optical materials.

Alloying properties: Molybdenum is often alloyed with other metallic elements to improve the properties of the material. For example, molybdenum alloys increase strength, wear resistance and corrosion resistance and are widely used in the aerospace, electronics and chemical industries.

Molybdenum is a chemically stable element that exhibits good corrosion resistance under a variety of conditions, the ability to react with oxygen and non-metallic elements to form compounds, and the ability to form a wide range of complexes and alloying properties. These properties give molybdenum important application value in many different fields.
