​In recent years, the field of thermal management materials has seen significant advancements. One such area of focus has been the modification of the surface properties of aluminum powders to improve their thermal performance. As a leader in the production of high-quality nano aluminum powders, SAT NANO has played a key role in these efforts. In this blog post, we will explore the methods and benefits of surface modification of aluminum powder.

Stealth technology has come a long way since its inception during World War II. The use of radar-absorbing materials and electromagnetic signature reduction techniques has helped to make aircraft, ships, and vehicles less detectable to the enemy. However, the holy grail of stealth technology has always been invisibility – the ability to render an object completely invisible to the naked eye. In this blog post, we will examine the potential of nanomaterials to revolutionize the field of stealth technology by creating invisible cloaks.

Copper is different from metals such as aluminum and nickel in that it is difficult to form a dense and stable intrinsic passivation layer on its surface. Therefore, the exposed copper surface will be continuously oxidized and corroded by oxygen and water vapor in the air. The smaller the particle size and larger the specific surface area of copper powder, the easier it is to rapidly oxidize to produce products such as cuprous oxide (Cu2O) and copper oxide (CuO). This oxide insulation layer significantly reduces the conductivity of copper powder and hinders particle sintering connection, resulting in degradation of the performance of the conductive paste.

On unsaturated metal sites of metal oxides or semiconductor oxides (such as Ti4+, Fe3+), water molecules first adsorb in molecular form, followed by O-H bond cleavage, resulting in bridge or terminal hydroxyl groups (M-OH) and surface hydrogen atoms. The thermodynamic driving force of this process comes from the strong Lewis acidity of metal ions, making water molecules easy to dissociate. Both experiments and DFT calculations indicate that surfaces covered with low oxygen tend to dissociate and adsorb, while surfaces covered with high oxygen tend to adsorb molecules.

Cobalt Oxide Nanopowder is a type of nanoparticle derived from Cobalt, a transition metal. Due to its unique properties such as excellent magnetic, catalytic properties, and high stability, it has been used in various industries for many years. Cobalt Oxide Nanopowder is finely grained and can range from 10 to 100 nanometers in size.
