What Is the Function of Molybdenum Seed Holder in Sapphire Crystal Growth? 179

What Is Molybdenum Seed Holder? Molybdenum seed holder, also named molybdenum chuck, is widely used in vacuum furnaces and sapphire crystal growth furnaces to connect the seed rod for crystal growth. The seed rod inserted into the moly chuck, and fixed by a molybdenum pin or taper. The purity of this holder is above 3N5, the density can reach 10.0g/cm3, and the working temperature is controlled below 1700℃. Regularly, the diameter ranges from 10mm to 100mm and length ranges from…

Why Molybdenum Hammer Is Important in the Monocrystalline Silicon Growth? 181

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,…

Duplex Stainless Steel Containing Molybdenum Is Used in Xiamen Mountains-to-Sea Trail 207

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? 232

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…

Why Tungsten Crucibles and Molybdenum Crucibles Are Used for Sapphire Crystal Growth? 227

Crystal growth is the foundation of many cutting-edge technologies such as sapphire touchscreens, LED lighting components, solar cells and high-power lasers. Corrosion resistance, creep resistance and high temperature properties enable tungsten and molybdenum crucibles to be used for high temperature sapphire crystal growth processes. Crucibles made of tungsten and molybdenum materials perform well in the heat exchanger method (HEM) process for melting and solidification of single crystals. Better sapphire yield and quality can be achieved when the sapphire is easy…

Types of Molybdenum Crucibles Manufactured by Different Processes 194

Molybdenum is a refractory metal known for its excellent strength at high temperatures, high melting point of 2610 ℃, and high corrosion resistance. This high melting point makes molybdenum ideal for use as evaporation boats or crucibles, and for processing nuclear fuel pellets at temperatures up to 1650°C. products made of molybdenum are durable enough to withstand repeated rough handling. Molybdenum will not oxidize to any significant degree below 400 ℃ in air or an oxygen-containing atmosphere. At 400 ℃…

Advantages of Molybdenum Disulfide Coating Based on MoS2 253

Molybdenum is a lustrous silver metal found in the earth’s crust at 1.5 ppm. In many cases, it is very similar to tungsten, which is often paired with tungsten in the transition series of the periodic table, but their chemistry often exhibits more pronounced differences than expected. The metal can withstand extremely high temperatures without significantly changing, expanding or softening. This ability makes its engagement in high temperature situations very useful. Typical applications of molybdenum are various, such as crucibles,…
