Silver (Ag) Micron Powder

Purity: 99.99 %, Size: 3 µm

Silver (Ag) Micron Powder is a high-purity (99.99%) metallic powder characterized by a precise 3 µm particle size, engineered for industrial applications where the extreme reactivity of nanoparticles is not required, but superior electrical and thermal performance is essential. With a high density of 10.491 g/cm³ and a low electrical resistivity of 108.4 microhm-cm, this powder provides an excellent conductive path and structural stability in various matrices. Unlike nanometric dispersions, this micron-scale powder offers easier handling and improved compatibility with traditional thick-film technologies and metallurgical processes. As a research-grade material, it is designed for professional use in environments requiring high-purity crystalline structures. To maintain its chemical integrity and prevent premature oxidation, this powder should be handled by experts and stored in a cool, dry place away from direct sunlight.
