Why Molybdenum Hammer Is Important in the Monocrystalline Silicon Growth? 140

What Is Molybdenum Hammer? The hammer is usually made of tungsten and molybdenum materials as it is used in high temperature furnaces that require the materials to be heat resisting. It is mainly used to connect molybdenum seed holder and tungsten wire rope, and is hung on the suspension clamp or jumper the bottom, increasing the clamp vertical load heavy objects. Although the product can be made from both tungsten and molybdenum metals, as tungsten price is higher than molybdenum,…

Types of JEOL’s EB Tungsten Filament 160

What Is JEOL’s EB Tungsten Filament？ Evaporation source materials used for vapor deposition require excellent electrical conductivity, high melting point and low vapor pressure. Therefore, many vapor deposition accessories are made of tungsten. Filaments/heaters made of tungsten have the characteristics of high melting point, low thermal expansion coefficient, good corrosion resistance and long evaporation life. Japan Electron Optical Laboratory is the full name of JEOL. After decades of exploration and research by the world’s top scientific instrument manufacturers, they created…

Will Molybdenum Plates Replace Graphene in the Electronics Industry? 145

Molybdenum is the most widely used materials in the processing industry. It can be used in the iron and steel industry, most of which are industrial molybdenum oxide briquette directly used for steelmaking or cast iron, a small part is smelted into ferromolybdenum and then used in steelmaking, or synthesized with other metals to make molybdenum plates. Plates made of molybdenum or molybdenum alloy can improve the corrosion resistance, strength and wear resistance of the original metal. With the characteristics…

What Are Differences of Tungsten Copper Foils, Sheets and Blocks 153

What do you know about tungsten copper foils, strips, sheets, plates, or blocks? What are their differences? Actually, they are the same product with rectangular shape. To distinguish them, people often call them differently. Foils usually mean plates with thickness less than 0.1mm; strips mean thin and narrow plates; sheets mean plates with 0.1-2.0mm thickness; plates mean 2.0-10.0mm thickness and thickness above 10.0mm will be called blocks. Tungsten copper alloy is a refractory metal alloy of tungsten and copper which…

Duplex Stainless Steel Containing Molybdenum Is Used in Xiamen Mountains-to-Sea Trail 174

Carbon steel is widely used around the globe for the construction of bridges of sizes ranging from the very large to the very small, but now many bridges around the world are approaching the end of their useful life because carbon steel bridges do not have the corrosion resistance benefits offered by chromium, molybdenum and other alloying elements. The forward-looking design of the Soderstrom Bridge with duplex stainless steel highlights the benefits of building bridges from structural stainless steel in…

What Are Excellent Properties of Molybdenum Disulfide in High Temperature Grease? 201

Molybdenum disulfide (MoS2) is a naturally occurring black solid compound that is slippery to the touch. It transfers easily and adheres to other solid surfaces it comes in contact with. Its mineral form — called molybdenite — was often confused with graphite until the late 1700s. Both have been used for lubricating and writing materials for centuries. So, what are the excellent properties of MoS2 in high temperature grease? 1)it can improve the bearing capacity of the grease and make…
