Do you know the characteristics of spherical aluminum powder? As more and more aluminum pigment products find their way into our daily lives, aluminum pigments have gradually become familiar to people. Everyone knows that aluminum powder is the raw material for aluminum pigments—but how much do you actually know about spherical aluminum powder? Are you aware of its unique features? Let’s find out together with Xiaoyang’s editor!
Do you know the characteristics of spherical aluminum powder? Before diving into its features, let’s first get acquainted with spherical aluminum powder itself! As everyone knows, aluminum powder is a silvery-grayish powder—sometimes referred to as aluminum silver powder or simply "silver powder" in other regions. When observed under a microscope, aluminum powder typically appears as either perfectly round spheres or irregular, branch-like particles. Among these, the aluminum powder that exhibits a truly spherical shape is what we call spherical aluminum powder.
Spherical aluminum powder exhibits a strong metallic luster and boasts relatively high melting and boiling points, making it commonly used in refractory materials. As the particle size of spherical aluminum powder increases, its grayish hue gradually diminishes; conversely, as the particle size decreases, the gray tone slowly intensifies. Typically, after aluminum powder production is completed, Xuyang conducts thorough inspections of the powder, including particle size analysis, active aluminum testing, and impurity content evaluation.
Spherical aluminum powder plays an indispensable role in our daily lives, primarily used in solar cell pastes, the photovoltaic industry, chemicals, metallurgy, and other sectors. Additionally, it finds applications in powder coatings, inks, plastic color masterbatches, printing, imitation gold paper, imitation gold cards, gold films, textiles, fingerprint detection, fireworks, and more. However, when aluminum powder is used in water-based paints or paints containing acidic or alkaline components, it tends to oxidize and turn black. Therefore, users should exercise extra caution and avoid applying aluminum powder in such environments.
That’s all for today’s main content on "Characteristics of Spherical Aluminum Powder." Stay tuned to Xuyang’s editor for the next exciting update—right on time for you!
