High Purity Aluminum Al powder CAS 7429-90-5, 99%

Overview of Aluminum powder ：

Aluminum powder has a silver-white metallic luster, reflecting a strong metallic glow in the light. With a 2.7g/cm3 density, it has a lower density than most metal powders. The particle size of aluminum powder can be adjusted according to the production process; it can be a very fine powder or a material with a certain granularity. Aluminum powder has high chemical activity and can react with various substances. It is amphoteric and can react with both acids and bases. Aluminum powder is easily oxidized in humid air, forming a dense oxide film to prevent further oxidation of the aluminum inside. In addition, aluminum powder can also react with non-metallic elements, such as chlorine, fluorine, etc., to generate corresponding compounds. Although aluminum powder has high chemical activity, reacting violently with other substances at normal temperature and pressure is not easy. However, high concentrations of aluminum powder may spontaneously ignite under high temperature and pressure conditions, so the production and use environment needs to be strictly controlled. In production and use, contact between aluminum powder and humid air, acid, alkali, and other substances should be avoided to prevent danger. 

Technical Parameters of Aluminium Al powder CAS 74229-90-5

Features of Aluminum powder ：

Physical properties: aluminum powder is lightweight, has high floating force, covering power, and uniform reflection of light and heat. The aluminum powder particles are scaly, and the flake diameter-to-thickness ratio is about (40∶1) ~ (100∶1). When the aluminum powder is dispersed into the carrier, it is parallel to the substrate, many aluminum powders are connected, and the small and small particles are filled with each other to form a continuous metal film, which covers the substrate and reflects the light outside the coating. This characteristic gives the aluminum powder a high hiding power.

Shielding characteristics: Aluminum powder has good physical shielding performance. When the aluminum powder is dispersed in the carrier, it always makes itself parallel to the substrate coated by the carrier, forming a continuous layer of aluminum powder. The pores between the aluminum powder layers are interlaced, cutting off the pores of the carrier film so that external water and gas can not reach the substrate through the pores.

Optical properties: Aluminum powder made of aluminum, light color, high metallic luster. Its smooth surface reflects 60% to 90% of visible, ultraviolet and infrared light. The object is coated with a coating containing aluminum powder, and the surface is silver-white and bright, which is the characteristic of aluminum powder reflecting light. In addition, aluminum powder also has a "two-color effect" characteristic. In the carrier containing transparent pigments, aluminum powder's luster and color depth will change with the incident Angle and Angle of view of the incident light.

Chemical properties: Aluminum powder can dissolve in acid and alkali, while replacing hydrogen, insoluble in water. However, it is worth noting that aluminum powder will react chemically when it encounters a small amount of water or moisture, releasing hydrogen and heat. If the accumulated heat is not dispersed, it is easy to cause combustion and explosion.

FAQ：

Q1:

What is aluminum powder? 

Aluminum powder, also known as "silver powder," is a silver metallic pigment made of pure aluminum foil with a small amount of lubricant, which is crushed into a scaly powder and then polished. It has a lightweight, high floating force, strong hiding power, and good reflection performance to light and heat. Aluminum powder can also be turned into non-floating aluminum powder after special treatment.

Aluminum powder is widely used in many fields. For example, in the manufacture of fireworks, aluminum powder is often used to increase the brightness and color effect of fireworks. In the coating industry, aluminum powder is often used as a pigment, added to paints, inks and other products to provide metallic luster and anti-corrosion functions. In addition, aluminum powder also plays an important role in metallurgy, the chemical industry, aerospace, automobile manufacturing, and other fields.

Q2：

How to use aluminum powder? 

Additives: Aluminum powder can be added to chemical products, such as polyurethane foam, rubber, paint, etc. It needs to be evenly dispersed into the product during the addition process to achieve good results. To prevent sparks during the addition process, contact with oxidants, such as hydrogen peroxide, nitric acid, etc., should be avoided.

Metal thermions: Aluminum powder can be used as metal thermions to participate in combustion reactions. In this process, aluminum powder reacts with oxygen in the air to produce heat and aluminum oxide. This reaction can prepare metal oxides, synthesize certain chemicals, weld metals, etc.

Powder metallurgy: Aluminum powder can be used in powder metallurgy technology to prepare high-performance metal parts. In this process, the aluminum powder is mixed with other metal powders, and through high-temperature heat treatment, they are combined into one at the microscopic level.

Pressure sensors: Aluminum powder can be used to prepare pressure sensors. Mixing aluminum powder and polymer material, the composite material sensitive to resistance change is prepared. When the material is subjected to pressure, a small deformation will occur, resulting in a change in resistance to achieve the function of measuring pressure.
