What is spherical aluminum powder? It’s Xuyang’s editor here again with you all! Today, the editor would like to discuss some key questions about spherical aluminum powder. With rapid advancements in national science and technology, more and more people are starting to pay attention to the chemical industry. So, let’s dive into some essential knowledge about aluminum pigments today—specifically, what exactly is spherical aluminum powder?
What is spherical aluminum powder? First, let’s start by introducing aluminum powder—it’s a silvery-white to grayish powder, sometimes referred to as aluminum silver powder or silver powder in certain regions. As the particle size of aluminum powder increases, its grayish hue becomes less pronounced; conversely, as the particles grow smaller, the gray tone gradually intensifies. When viewed under a microscope, aluminum powder appears either as perfectly round spheres or irregular, branch-like particles, exhibiting a strong metallic luster and possessing relatively high melting and boiling points.
The aluminum powder that appears as a perfect sphere is indeed spherical aluminum powder. Spherical aluminum powder serves as a raw material for producing aluminum silver paste and is widely used across various industries. It is primarily employed in chemical raw materials, metal coatings, metallic pigments, paints, fireworks, and even finds applications in the metallurgical industry.
Large amounts of spherical aluminum powder can spontaneously ignite upon contact with water vapor. Moreover, when mixed with oxidizers, spherical aluminum powder forms an explosive mixture. It also reacts violently with gases such as fluorine and chlorine. Most seriously, contact with acids or strong alkalis can trigger the release of hydrogen gas, leading to combustion and even explosions. Additionally, significant quantities of spherical aluminum powder, when combined with air, can create an explosive mixture that will detonate if exposed to even a small spark at certain concentrations. Therefore, everyone should avoid being near large amounts of aluminum powder or in high-temperature environments to ensure their safety.
That’s all about “What is spherical aluminum powder”—we hope the editor’s explanation was helpful. Don’t forget to follow Xuyang’s editor for more exciting updates!
