Abstract
(EN)
This radio wave absorbing composition includes a magnetic powder and a binder. This radio wave absorbent includes a magnetic powder and a binder. The magnetic powder is a substituted hexagonal ferrite powder, the surface of which is treated with a surface treatment agent, and the surface treatment agent is a silicon-based compound. In addition, the binder is at least one resin selected from the group consisting of polyester and polycarbonate.
