Effect of molybdenum mesh on reaction performance
1.Characteristics of molybdenum mesh Molybdenum mesh is a metal mesh material mainly made of molybdenum. It is characterized by high strength and good corrosion resistance, and can withstand high temperature and high pressure reaction environments. In addition, molybdenum mesh has a high specific surface area and excellent thermal conductivity, which can improve the activity and stability of the catalyst. 2.The role of molybdenum mesh in the reaction As a catalyst carrier, molybdenum mesh plays an important role in reaction performance. Mainly include the following aspects: Increase the dispersion of active metals.Molybdenum mesh has a high specific surface area, which can increase the dispersion of active metals and improve the activity of the catalyst. In addition, molybdenum mesh can also adjust the response performance of the catalyst by changing the spacing between metals. Improve the mass transfer performance of the reaction.Molybdenum mesh has high thermal conductivity, which can improve the mass transfer performance of the reaction, promote the diffusion of reaction substances and the adsorption of catalysts. In addition, molybdenum mesh can also increase the contact area between reacting substances and catalysts, enhancing the rate and effect of the reaction. Enhance the stability of the catalyst.The high strength and good corrosion...

Thermophysical properties of molybdenum rods
1. High melting point The melting point of molybdenum rod is 2610°C, which is one of the highest melting points of all metals. This allows the molybdenum rod to maintain stability and strength at extremely high temperatures and therefore has a wide range of applications in high temperature environments. 2. Low thermal expansion coefficient The linear expansion coefficient of molybdenum rods is very small and the thermal expansion coefficient is low, which allows the molybdenum rods to maintain the stability of their shape and size at high temperatures, which is of great significance to the manufacturing of high-temperature equipment and components. 3. Good thermal conductivity Since molybdenum has a relatively large thermal conductivity, molybdenum rods have good thermal conductivity and are suitable for the production of various high-temperature thermally conductive components and devices.

What is molybdenum wire?
As a typical molybdenum product, molybdenum wire is a filament made by forging and drawing molybdenum bars or rods. It is a kind of molybdenum wire that continuously moves with a high-voltage electric field to cut the workpiece during wire cutting. A thin metal wire made of other chemical elements, called Molybdenum wire in English, contains as much as 99.90% molybdenum, and its diameter is generally between 0.02-12.00mm. It is worth mentioning that in order to further improve the performance of pure molybdenum wire and expand its application range, manufacturers often add elements such as lanthanum and yttrium during its manufacture. From the perspective of physical and chemical properties, molybdenum wire is generally silver gray or black in color (surface covered with graphite), has a higher melting point, higher density, higher tensile strength, lower resistivity, and smaller thermal expansion. coefficient, small elongation, good high temperature resistance, acid and alkali resistance and other characteristics. It should be noted that when heated in air, it will react with oxygen; the overall performance of doped molybdenum wire is generally better than that of pure molybdenum wire. From the perspective of production technology, pure molybdenum wire is a product that uses a hot and...

Introduction of Molybdenum Boat
As a typical product of transition metal molybdenum, molybdenum boat is also known as evaporated molybdenum boat or coated molybdenum boat, is made of molybdenum sheet or molybdenum base alloy by welding or high temperature stamping, is an important sintering carrier for molybdenum powder and other metal powder preparation. From the point of view of physical and chemical properties, molybdenum boat generally has high density, high melting point, high strength, low thermal expansion coefficient, high temperature resistance, corrosion resistance, good creep resistance, ductility and electrical and thermal conductivity characteristics. Note: The specific physical and chemical properties and uses of different materials of molybdenum boat there are some differences, such as pure molybdenum boat can withstand the temperature of about 1100°C, can be used as rare earth materials melting equipment and sintered tungsten oxide vessels; Molybdenum lanthanum alloy boat and TZM (molybdenum zirconium titanium) alloy boat can withstand the temperature of about 1900°C, suitable for working in high temperature environment. According to the different shapes, molybdenum boat has round, rectangular, square and trapezoid shapes; According to the different processing methods, molybdenum boats can be divided into stamping boats, folding boats, welding boats and riveted boats and other types; According to the...
