Spherical Carbonyl Iron Powder

Description

For 20 years, we have been dedicated to the research of carbonyl iron powder with a focus on microwave absorption and electromagnetic compatibility requirements. The result is the development of carbonyl iron powder with typical nanocrystalline characteristics, characterized by fine and uniform particle size, excellent flowability, high purity, and easy compatibility with adhesives. The absorption materials and electromagnetic compatibility devices made from this powder exhibit excellent processability, mechanical and thermal stability, reliability, outstanding absorption performance, and wide operating bandwidth. These products find extensive applications in military, radar, microwave communication, satellite ground stations, microwave instrument equipment, electromagnetic shielding (EMI) devices, and everyday microwave pollution absorption materials.

In recent years, we have further advanced its technology in the field of microwave absorption, developing high magnetic flux micro-nano sheet iron-based materials, as well as FeC composite materials.
