Characteristics

Product name:Zinc powder, zinc dust.
Appearance:Light grey globular powders.
Molecular formula: Zn
Molecular weight: 65.38
Melting point (℃): 419.6
Boiling point (℃): 907
Relative density (water=1): 7.13

Applications

It is mainly utilized to produce zinc-rich paint, organic synthesis and nonferrous metal alloy. It can also serve as catalyst and reducing agent.
Main performances of KFZn series zinc powder: High activity---The ratio of weight of metallic zinc to the gross weight of the zinc powder is over 97%,resulting in high performance on corrosion resistance High dispersibility---High roundness and uniform granularity of the zinc powder facilitate the production of high quality anti-corrosive paint. Low impurity---Harmful substances such as lead and cadmium are limited to 0.003% so that it is friendlier to health and environment.
