Products Description
Molybdenum electrode, as an electrode with transition metal molybdenum as the main raw material, plays a vital role in high-temperature industry due to its unique physical and chemical properties.
The main component of molybdenum electrode is molybdenum, and its content is usually above 99.95%. This high-purity molybdenum electrode has significant advantages such as high high-temperature strength, good high-temperature oxidation resistance, long service life, and corrosion resistance. In addition, the density of molybdenum electrode is greater than 10.15g/cm³, which ensures its stability and durability in high-temperature environments. The diameter of molybdenum electrode is generally between 20mm and 152.4mm, and the length can reach 1500mm, which meets the needs of various high-temperature industrial applications. Its silvery white or steel gray metallic luster and smooth surface make molybdenum electrode visually attractive.
The production process of molybdenum electrodes includes several key steps, including raw material preparation, mixed molding, sintering, and surface treatment. First, high-purity molybdenum powder needs to be prepared as raw material and mixed with other additives to form the desired mixture. Next, the mixture is pressed into an electrode of the desired shape and sintered in a high-temperature and high-pressure atmosphere to increase its density and mechanical strength. Finally, according to application requirements, the sintered molybdenum electrode is polished, plated, or otherwise coated to enhance its corrosion resistance, conductivity, or other properties. Molybdenum electrodes have a wide range of applications, mainly including glass manufacturing, electronic component manufacturing, vacuum heat treatment, aerospace and other fields. In the glass manufacturing process, molybdenum electrodes are the core components of the heating element. Their unique physical and chemical properties enable them to maintain good performance at high temperatures, thereby ensuring the quality and optical properties of the glass. In the fields of electronic component manufacturing and vacuum heat treatment, the high temperature stability and good electrical conductivity of molybdenum electrodes make them key materials. In addition, in the field of aerospace, the lightweight and high temperature stability of molybdenum electrodes also provide them with broad application prospects.
Compared with tungsten electrodes, molybdenum electrodes have lower density and better thermal and electrical conductivity. This makes molybdenum electrodes have broad application prospects in aerospace, aviation and other fields, which can significantly reduce the weight of products and improve energy efficiency and operating performance. However, tungsten electrodes are favored in TIG welding and other similar welding processes due to their high melting point, excellent corrosion resistance and high density. Therefore, when selecting electrode materials, it is necessary to comprehensively consider the specific application requirements and working environment.
