Zinc (Zn) Micron Powder (99.9%, 3 µm)

Description

Zinc (Zn) Micron Powder (99.9%, 3 µm)

Zinc (Zn) Micron Powder with 99.9% purity and an average particle size of 3 µm is a fine, high-performance metallic powder widely used across industrial, chemical, and metallurgical applications. With its hexagonal crystal structure, excellent electrical conductivity, and moderate hardness (Mohs 2.5), zinc powder provides outstanding versatility in both functional and structural uses.

Its relatively low melting point (419.5 °C) and boiling point (907 °C) make it suitable for casting, alloying, and catalytic processes. Due to its strong reducing power and reactivity, zinc micron powder is essential in pyrotechnics, chemical synthesis, and galvanic applications.
