What Are the Applications of Molybdenum Substrates?

Molybdenum substrates are essential components in a variety of industries, thanks to the unique properties of molybdenum metal, such as its high melting point, excellent thermal conductivity, and resistance to corrosion. 

These properties make moly substrates highly suitable for applications in electronics, aerospace, and energy sectors, particularly in environments that demand reliability under high temperatures and pressure.

1. Semiconductor Industry

One of the primary uses of Mo substrates is in the semiconductor industry, where they serve as a stable base for the deposition of thin films. Mo substrates provide a smooth and durable surface for creating thin-film semiconductors and integrated circuits (ICs). Their high thermal conductivity helps dissipate heat during manufacturing, preventing thermal damage to sensitive components. Additionally, moly substrates can withstand the high temperatures required during the fabrication of electronic components such as power devices and optoelectronic devices, including LEDs and lasers.

2. Thin Film Deposition

Moly substrates are widely used in thin-film deposition processes, such as sputtering and chemical vapor deposition (CVD), where materials are deposited onto a substrate to form thin, functional layers. These films are commonly used in solar cells, displays, and photovoltaic devices. Molybdenum's high melting point and excellent heat resistance ensure that it remains stable during the deposition process, providing a reliable foundation for high-quality films.

3. Aerospace and High-Temperature Usages

Due to its high thermal conductivity and resistance to oxidation, molybdenum is widely used in aerospace and high-temperature environments. Mo substrates are found in components of rocket engines, turbine blades, and aircraft parts that must endure extreme heat and pressure. Its ability to maintain structural integrity at elevated temperatures makes molybdenum ideal for these demanding usages.

4. Energy and Nuclear Usages

Moly substrates are also used in energy sectors, particularly in nuclear reactors and energy storage devices. Their resistance to corrosion and radiation makes them effective in nuclear applications, where materials are exposed to high radiation levels.

Conclusion

Molybdenum substrates play a critical role in several high-performance industries. Their thermal stability, conductivity, and durability make them essential in semiconductor manufacturing, thin-film deposition, aerospace, and nuclear usages. As industries continue to evolve, the demand for moly substrates is likely to grow, driven by technological advancements and the need for materials that can withstand extreme operational conditions.

Properties

Molybdenum is known for its robustness in high-temperature applications. It has a high melting point and can maintain its structural integrity even at extreme temperatures. The metal’s excellent thermal and electrical conductivity makes it ideal for applications that require effective heat dissipation. Molybdenum also exhibits high resistance to corrosion, oxidation, and wear, even in harsh chemical environments.

One of the most significant advantages of moly substrates is their ability to withstand thermal cycling without degradation. This property is particularly beneficial for devices that experience fluctuating temperatures. Furthermore, moly substrates offer a smooth surface finish, which is crucial for applications that require precision and minimal surface defects, such as in the fabrication of semiconductors.

Applications

Moly substrates are widely used in the manufacture of integrated circuits (ICs), LEDs, and solar cells. In the semiconductor industry, moly substrates provide a stable base for thin-film deposition, allowing for the creation of thin, high-performance films that can withstand high temperatures during the fabrication process. Additionally, moly substrates are often used in aerospace applications, such as in rocket nozzles and aircraft parts, due to their ability to perform under extreme conditions.

Electron Beam Tungsten Filament Price in Early November 2024

The price of φ0.65mm electron beam tungsten filament is USD 2.50/PC, EXW XIAMEN, CHINA in the first half of November 2024. 

electron beam tungsten filament price photo

Tungsten filaments, also called cathodes or electron emitters or electron sources, are mainly made of high-quality tungsten. Of all pure metals, tungsten has the highest melting point (3422°C), the lowest vapor pressure at temperatures above 1650°C, and the highest tensile strength. Tungsten also has the lowest coefficient of thermal expansion of all pure metals. This combination of properties makes tungsten an ideal material.

Tungsten can be used in both thermionic electron guns and field-emission (CFE) electron guns. Electron beams come from filaments made of various materials. The most common is the tungsten hairpin gun, which is widely used in scanning electron microscopes, transmission electron microscopes, and microprobe systems. This filament is a tungsten ring that acts as a cathode. Apply voltage to the loop to heat it up. The anode, which is positive relative to the filament, forms a strong attraction to electrons. This causes electrons to be accelerated towards the anode. Some accelerate near the anode and down the column to the sample.

An electron gun works at a high temperature, which is required for thermionic emission. For this, a filament or the cathode should be of a material that has a high melting point in order for it to continuously emit electrons. Tungsten filament is folded with various shapes to help in focusing the electron beam.

2% Ceriated Tungsten Electrode Price in Early November 2024

The price of φ1.6x175mm ceriated tungsten electrode is USD0.50/PC, EXW XIAMEN, CHINA in the first half of November 2024. 

ceriated tungsten electrode price photo

Ceriated tungsten electrode (WC20) is alloyed with about 2% cerium oxide. It is a non-radioactive, refractory or non-consumable metal electrode material, which is the preferred substitute for thorium tungsten electrodes. Regular diameter of the electrode is between 0.5mm and 12.0mm, and the length is 150mm and 175mm.

The addition of this small percentage of cerium oxide increases the electron emission qualities of the electrode which gives them a better starting characteristic and a higher current carrying capacity with no spitting. With the increase of cerium oxide content, the ablation resistance and arc starting of ceriated tungsten electrode will increase; with the increase of use time, the welding performance will gradually decrease.

The electrode has excellent arc starting properties at low current, and can operate successfully with AC or DC electrode negative. If used on higher current applications, the cerium oxide June be concentrated to the excessively hot tip of the electrode. In addition, WC20 is also used in inert gas shielded arc welding, hydrogen atom welding, argon arc surfacing, pulse argon arc welding, plasma welding, plasma cutting, plasma spraying, plasma melting, etc. The welding materials can be carbon steel, stainless steel, silicon copper, copper, bronze, titanium and so on.

Corrosion resistance, creep resistance and high temperature performance make molybdenum made rings very suitable for high temperature crystal growth processes. When sapphire is easy to extract, higher sapphire yield and quality can be achieved. The molybdenum-based ring has heat resistance and a smooth surface, making it durable and cost-effective.

The surface roughness of the molybdenum ring needs to be higher than 1.6 µm. When the surface of the ring is rough, the sapphire is not easy to take out and it is easy to damage the crystal. In addition, the ring will be damaged in the process. Chinatungsten Online's ultra-smooth ring eliminates these problems. Sapphire manufacturers can benefit from this product because it eliminates complex and expensive processes. In addition, the smooth surface is resistant to corrosion caused by aggressively molten sapphire. This function can extend the service life of reusable rings.

Moly rings for sapphire growth furnaces are available with a variety of dimensions including round, in numerous standard diameters and wall thicknesses. Custom configurations are available. In addition, many other components for these furnaces are also customized.
