Category Functions and application of molybdenum

Melting point of molybdenum(2625°C), boiling point (4600°C), hardness (5.5), and density (10.2 g/cm3), making it a good conductor of electricity and heat. Molybdenum offers the following performance advantages: Applications of molybdenum Molybdenum metal has a wide range of applications in electronic devices such as tubes, transistors and rectifiers Double-sided polished molybdenum substrate (mirror and surface roughness≤0.03μm), applied toLEDlight-emitting chip, replace sapphire as substrate, with better heat dissipation。

Wafer substrates made of molybdenum, molybdenum copper and materials: For LED lamps to be durable, reliable and robust components are required. Molybdenum and MoCu wafer substrates, the service life of LED chips can easily reach 100,000 hours. Semiconductor layers in LED chips convert electrical current into light. The semiconductor layer consists of an electron region (N-type doping) and a hole region (P-type doping). Electric current flows through the semiconductor layer, and electrons combine with holes to emit light in the form of photons. The remaining energy is released in the form of thermal radiation, and the temperature can reach 85…

Laser molybdenum retroreflector are more resistant to friction Molybdenum is a silver-white metal with high hardness, Mohs hardness of 5-5.5, atomic radius of 0.14nm, atomic volume of 235.5px/mol, and coordination number of 8. The mirror made of molybdenum is more resistant to friction High reflectivity and stable performance Molybdenum retroreflectors do not need to be coated, and the reflectivity at a wavelength of 10.6 μm reaches more than 94%. It is extremely difficult for molybdenum to lose seven or eight electrons. This determines that the chemical properties of molybdenum are very stable. High temperature resistance, more corrosion resistance Molybdenum has…

Molybdenum squares and molybdenum discs can be plated with nickel, silver and gold on the surface according to different needs. The advantages of different coatings are as follows: First, nickel plating on the surface: Second, gold plating on the surface: 1. Gold plating has low contact resistance, good electrical conductivity, easy welding, strong corrosion resistance, and certain wear resistance (referring to hard gold), so it is widely used in precision instruments, printed circuit boards, integrated circuits, tubes Shells, electrical contacts and other aspects have a wide range of applications. 2. The appearance of the gold-plated layer is golden yellow and…
