The scientific and technological charm of molybdenum targets

Fasteners play an indispensable role in our daily lives and industrial production. From simple furniture assembly to complex aircraft manufacturing, a wide variety of fasteners are used. Among many fastening devices, molybdenum fasteners are gradually attracting people's attention due to their excellent performance and wide range of applications. Today, let us explore this mysterious molybdenum target together.

First, we need to understand what molybdenum is. Molybdenum, whose element symbol is Mo, is a silver-white metallic element and is a transition metal. Molybdenum is hard in texture, has strong wear resistance, and has good strength and hardness at high temperatures. Therefore, it is widely used in various high-strength, high-wear-resistant, and high-temperature-resistant environments.

The so-called molybdenum targets are various targets made of molybdenum as the main material, such as molybdenum targets, molybdenum sheets, etc. Due to the special properties of molybdenum, molybdenum targets have many advantages that other materials cannot match.

First, molybdenum targets have extremely strong high temperature resistance. It can still maintain good mechanical properties and hardness at temperatures up to 1500°C, which makes it widely used in aviation, aerospace, nuclear industry and other fields.

Second, molybdenum targets have excellent corrosion resistance. In a humid environment, many metals will be oxidized and corroded, but molybdenum can remain stable, which makes it important in chemical equipment, medical equipment and other fields.

Third, the wear resistance of molybdenum targets is also very outstanding. Whether it is sliding friction or rolling friction, molybdenum can maintain a low wear rate, so molybdenum targets are the first choice for equipment that requires high precision and long life.

However, although molybdenum targets have so many advantages, we also need to pay attention to some problems in actual use. For example, because molybdenum is difficult to process, making molybdenum targets requires specialized equipment and technology. At the same time, due to its relatively high price, economics should be fully considered when choosing to use it.

In addition, although molybdenum itself is harmless to the human body, at high temperatures it can react with oxygen in the air to form toxic oxides. Therefore, when using molybdenum targets, protective measures should be taken to avoid prolonged exposure to high temperatures.

In general, molybdenum targets are gradually becoming the new favorite in the industrial field due to their excellent performance and wide application prospects. Whether it is aerospace exploration in extreme environments or precision equipment in complex environments, molybdenum targets have demonstrated their unique value. We have reason to believe that with the development of science and technology, the application of molybdenum targets will be more extensive, and its scientific and technological charm will be more brilliant.

Performance of molybdenum sputtering target
Molybdenum sputtering targets perform identically to their source materials (pure molybdenum or molybdenum alloys). Molybdenum is a metal element mainly used in steel. After industrial molybdenum oxide is pressed, most of it is directly used in steelmaking or cast iron. A small amount of molybdenum is smelted into ferromolybdenum or molybdenum foil and then used in steelmaking. It can improve the strength, hardness, weldability and toughness of the alloy, as well as its resistance to high temperatures and corrosion.

Application of molybdenum sputtering targets in flat panel displays
In the electronics industry, the applications of molybdenum sputtering targets are mainly concentrated in flat-panel displays, thin-film solar cell electrodes and wiring materials, and semiconductor barrier materials. These materials are all based on molybdenum with high melting point, high conductivity, and low specific impedance. As the base material, it has good corrosion resistance and environmental protection performance. Molybdenum has the advantages of only half the specific impedance and film stress of chromium, and has no environmental pollution problems. It has become one of the preferred materials for sputtering targets for flat panel displays. In addition, adding molybdenum elements to LCD components can greatly improve the brightness, contrast, color and life of the LCD.

Application of molybdenum sputtering target in thin film solar photovoltaic cells
CIGS is an important type of solar cell used to convert sunlight into electricity. CIGS is composed of four elements: copper (Cu), indium (In), gallium (Ga) and selenium (Se). Its full name is copper indium gallium selenide thin film solar cell. CIGS has the advantages of strong light absorption capacity, good power generation stability, high conversion efficiency, long power generation time during the day, large power generation, low production cost, and short energy recovery period.

Molybdenum targets are mainly used to form the electrode layer of CIGS thin film batteries through sputtering. Molybdenum is located at the bottom of the solar cell. As the back contact of the solar cell, it plays an important role in the nucleation, growth and morphology of CIGS thin film crystals.
