Silver (Ag) Micron Powder (99.99%, 3 µm)

Description

Silver (Ag) Micron Powder (99.99%, 3 µm)

Silver (Ag) Micron Powder is a high-purity metallic powder with excellent electrical conductivity, thermal conductivity, catalytic performance, and antibacterial activity. Produced with 99.99% purity and an average particle size of 3 µm, this fine dark gray metallic powder exhibits a cubic crystal structure and is widely used in electronics, catalysis, alloys, and advanced industrial applications.

Unlike nanosilver powders, which are widely used for antibacterial and biomedical applications, micron-scale silver powders are primarily utilized in electronics, conductive materials, catalysts, and industrial processes, where high conductivity and material stability are required.
