Molybdenum plate is a special metal sheet made from molybdenum metal with a purity of over 99.95%, boasting a melting point as high as 2620°C, one of the highest among metals. This characteristic, combined with its other exceptional physical and chemical properties, makes molybdenum plate the preferred material in extreme environments. Here’s a detailed explanation of why:
I. Stability Derived from High Melting Point
- The high melting point of molybdenum plate grants it excellent stability in high-temperature environments, enabling it to withstand applications under extreme heat. This characteristic makes molybdenum plate an ideal choice for furnace chambers, spacecraft components, and containers for high-temperature molten metals.
II. Outstanding Corrosion Resistance
- Molybdenum exhibits strong chemical stability, resistant to acids, bases, solvents, gases, and other external factors.
- During further oxidation, molybdenum forms a stable oxide protective layer that effectively prevents corrosion.
- Based on molybdenum’s outstanding corrosion resistance, it has important applications in oil wells and natural gas pipelines in the oil and gas industry, rocket engines and high-temperature components in the aerospace industry, and other fields.
III. Excellent Mechanical Properties
- Molybdenum plate has a high density (reaching 10.2g/cm³), which gives it excellent mechanical properties such as high strength, high hardness, and good tensile resistance.
- These properties make molybdenum plate widely used in electronic components, vacuum equipment, the chemical industry, aerospace, and other fields.
IV. Superior Thermal Conductivity and Electrical Conductivity
- Molybdenum plate is among the best metals in terms of thermal conductivity and electrical conductivity, making it play a crucial role in electronic devices, power generation equipment, thermal instruments, optical fiber communications, and other fields.
However, molybdenum plate also has some limitations, such as relatively high price, difficulty in processing (especially when manufacturing complex-shaped parts), potential oxidation at extremely high temperatures (above 600°C), and poor ductility at room temperature. Overall, in extreme environments, the advantages of molybdenum plate far outweigh its limitations, making it still a preferred material.
