Ferromagnetic metal particles of iron alloyed with Ti, V, Cr, Mn, Co, Ni, Cu, Zn, Si, P, Mo, Sn, Sb and Ag coated with mono- or dialkoxysilanes

摘要

Ferromagnetic metal particles are disclosed, which have a silane compound on the surface thereof. The silane compound is represented by the formula: Rn-Si-(OR')4-n wherein R and R' each represent an alkyl group and n represents 2 or 3. The ferromagnetic metal particles have excellent oxidation stability and corrosion resistance. Furthermore, the ferromagnetic metal particles have good dispersibility within a binder when used in connection with producing a magnetic recording medium.
