Nanometer aluminum powder is a kind of nanometer powder material mainly composed of aluminum. It has high purity, high specific surface area and excellent physical and chemical properties, and is an important representative of nanomaterials.
One of the main characteristics of nanometer aluminum powder is its very small particle size. Generally, 40นาโนเมตร, 70นาโนเมตร, 100นาโนเมตร, 200นาโนเมตร, 800นาโนเมตร, has a higher specific surface area, providing more active surfaces, which in turn enhances its chemical reactivity and catalytic activity.
Nanometer aluminum powder has been widely used in many fields. First, because of its high catalytic activity and surface activity, nano-aluminum powder is often used as an important part of the catalyst. It can be used in oxidation reaction, reduction reaction, reforming reaction and other chemical reactions to promote the reaction rate and improve product selectivity. นอกจากนี้, nano-aluminum powder can also be used in catalyst carriers, fuel additives and energy storage materials.
นอกจากนี้, nano-aluminum powder is also used in rocket propellants, combustion enhancers and welding materials. In rocket propellants, nano-aluminum powder can be used as an important component of high-energy fuel, providing higher combustion efficiency and thrust. In the combustion enhancer, the nano-aluminum powder can be used together with the oxidant to increase the energy release of the combustion reaction and the flame temperature. นอกจากนี้, nano-aluminum powder can also be used to prepare high-performance welding materials to improve the strength and stability of welded joints.
