Abstract
Provided are a ferrite powder that suppresses decreases in saturation magnetization and decreases in filler filling ratio and also suppresses inhibition of resin curing, and a method for producing the same. A ferrite powder composed of spherical ferrite particles, wherein the ferrite powder contains iron (Fe) 54.0-70.0 mass % and manganese (Mn) 3.5-18.5 mass %, has an average volume particle size of 2.0-20.0 μm, and has a carbon content of 0.100 mass % or lower.
Claims5
A ferrite powder comprising highly spherical ferrite particles,
- wherein the ferrite powder contains 54.0 to 70.0 mass % iron (Fe) and 3.5 to 18.5 mass % manganese (Mn), and
- wherein the ferrite powder has a volume average particle size of 2.0 to 20.0 μm and a carbon content of 0.100 mass % or less.
