Molybdenum is a silvery-white metal with a hard texture and a high melting point of 2620°C, second only to tungsten and rhenium, making it a key member of the refractory metal class. Physically, molybdenum exhibits excellent thermal and electrical conductivity. While its electrical conductivity is inferior to that of metals like copper and silver, it maintains relatively stable electrical conductivity at high temperatures. Molybdenum also possesses high strength and hardness, maintaining excellent mechanical properties even at high temperatures and resisting deformation or damage.
Molybdenum is chemically stable and, at room temperature, does not react with most chemicals. However, at high temperatures or in highly oxidizing environments, it reacts with oxygen and other substances to form oxides. This property also makes molybdenum uniquely valuable in high-temperature oxidation protection. For example, molybdenum oxides can form a dense protective film at high temperatures, preventing further oxidation of the underlying metal and thereby extending the lifespan of the metal.
Molybdenum has a wide range of applications and is a key element in the steel industry. In the steel industry, molybdenum is a key alloying element. Steels with added molybdenum possess increased strength, hardness, and wear resistance, as well as excellent corrosion and heat resistance. This type of steel is widely used in the manufacture of various mechanical parts, tools, and molds, such as crankshafts and gears for automobile engines, as well as large steel structures for construction. The excellent properties of molybdenum steel enable these products to operate stably and long-term in harsh operating environments, improving production efficiency and product quality.
In the electronics industry, molybdenum is a key material in the manufacture of electronic components such as electron tubes, transistors, and integrated circuits. Molybdenum’s high melting point and excellent electrical conductivity enable it to withstand high temperatures and high currents, ensuring the stable operation of electronic devices. For example, molybdenum wire is widely used in the manufacture of gates and anodes for electron tubes, precisely controlling the flow of electrons and achieving signal amplification and conversion.
In the aerospace industry, molybdenum and its alloys play an irreplaceable role. Because aircraft operate under high temperatures, high pressures, and high speeds, the performance requirements for materials are extremely high. Molybdenum alloys, with their high strength, hardness, and excellent high-temperature stability, can withstand the thermal and mechanical stresses of extreme conditions. Therefore, they are used in the manufacture of key components such as rocket engine nozzles and spacecraft thermal protection systems.
Molybdenum also has important applications in the chemical and energy sectors. In the chemical industry, molybdenum catalysts are used in processes such as petroleum refining and ammonia synthesis, improving reaction selectivity and efficiency. In the energy sector, molybdenum-based materials are used in the manufacture of control rods and fuel cladding in nuclear reactors, ensuring the safe use of nuclear energy.
Molybdenum, the toughest blade in the industrial furnace, plays a key role in various fields with its outstanding performance and wide application, driving the continuous development of modern industry and contributing significantly to the progress of human society.
