Antimony (Sb) Micron Powder (99.99%, -325 mesh)

Description

Antimony (Sb) Micron Powder (99.99%, -325 mesh)

Antimony (Sb) Micron Powder with 99.99% purity and a particle size of -325 mesh is a high-quality fine powder widely used in alloys, electronics, and industrial applications. With its rhombohedral crystal structure, moderate hardness (Mohs 3.25), and good electrical resistivity (39.1 µΩ·cm), it provides unique functional advantages in conductive, catalytic, and metallurgical processes.

Antimony exhibits excellent thermal stability, corrosion resistance, and alloying capability. Due to its relatively low melting point (630.5 °C), it is especially suitable for low-melting alloys, coatings, flame retardants, and precision manufacturing processes.
