CAS：7440-50-8
Product specification: 10-30nm
Molecular formula: Cu
Molecular weight: 63.55
Physical and chemical properties: purple-brown or purple-black powder
Applications of Nanometer copper powder
1. conductive paste:
The inner and outer electrodes of traditional MLCC (multilayer ceramic capacitor) are made of precious metals. With the increase in the price of precious metals and the decrease in the profit of MLCC, the base metal electrode multilayer ceramic capacitor has become a more economical substitute for the traditional noble metal electrode design. Nano-copper powder mixed with the copper electronic paste can sinter an electrode with a thickness of only one micron, which can optimize the microelectronic process, meet the miniaturization requirements of MLCC devices, replace precious metal electronic paste such as silver and electricity, and greatly reduce the cost. Micro-nano metal powders (palladium, silver, nickel, copper, etc.) account for more than 5% of the structural cost of MLCC (5% in low-capacity MLCC and 5%-10% in high-capacity MLCC). In order to adapt to the cost reduction trend and lightweight development direction of MLCC in recent years, monodisperse micro-nano copper powder, as an important substitute material for micro-nano metal powders (palladium, silver, and nickel), has a huge market scale and development potential, but it also requires further improvement on the specifications of micro-nano copper powder used. MLCC with an internal electrode thickness of 2-3 microns requires the metal crystal to be spherical or nearly spherical in shape, with the particle size controlled below micron level, preferably 0.2-0.7 microns and evenly distributed.
2. Solid lubricant
Nano-copper powder used as the solid lubricant is one example of nano-materials application. The ultrafine copper powder can be dispersed in various lubricating oils in a proper way to form a stable suspension. This kind of oil contains millions of ultrafine metal powder particles per liter, which combine with the solid surface to form a smooth protective layer, and at the same time, micro-scratches are filled, thus greatly reducing friction and wear, especially under heavy load, low speed, and high-temperature vibration conditions.
3. Efficient catalyst
Micro-nano copper powder has a relatively large specific surface area and high surface activity. As a catalyst, it can play a catalytic role in many organic reactions and show high catalytic activity. For example, the micro-nano copper powder can also catalyze the polymerization of acetylene in the process of making conductive fibers and partially replace precious metals such as platinum and ruthenium in the process of automobile exhaust treatment, thus completing the conversion of CO to CO2 in exhaust gas that pollutes the environment.
4. High-performance engineering materials
Nano-copper powder is the basic raw material for preparing nanocrystalline copper. Compared with general coarse-grained copper, nano-copper powder has higher hardness, tensile strength, and thermal conductivity. High-density and high-purity nano-copper has good superplastic ductility and can be widely used in the field of engineering materials.
5. Antibacterial materials
In terms of antibacterial properties, the researchers compared the antibacterial properties of nano-copper and nano-silver to different strains and found that the antibacterial properties of nano-copper and nano-silver were different for different strains.Generally speaking, metallic copper shows strong antibacterial properties, high chemical stability and environmental safety, and low price. Therefore, the antibacterial properties of nano-copper can be effectively utilized.
Price of Nanometer copper powder
Nanometer copper powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Nanometer copper powder. A large amount of large amount will be lower. The price of Nanometer copper powder can be found on our company's official website.
